+# Grid Rendering Pipeline
+
+## Overview
+
+The Grid rendering pipeline handles multi-layer tilemap rendering with chunk-based caching for optimal performance. It supports arbitrary numbers of rendering layers, viewport culling, zoom, and entity rendering.

+
+---
+
+## Architecture Overview
+
+### Layer-Based Rendering
+
+Grids render content through **layers** rather than per-cell properties. Each layer is either a `ColorLayer` (solid colors) or `TileLayer` (texture sprites).
+
+**Render order is determined by z_index:**
+- Layers with `z_index < 0` render **below** entities
+- Entities render at the z=0 boundary
+- Layers with `z_index >= 0` render **above** entities (overlays)
+
+Within each group, lower z_index values render first (behind higher values).
+
+```
+z_index: -3    -2    -1    0    +1    +2
+         |     |     |     |     |     |
+       [background] [tiles] [ENTITIES] [fog] [UI overlay]
+```
+
+### Chunk-Based Caching
+
+Large grids are divided into **chunks**. Each chunk maintains its own `sf::RenderTexture` that caches the rendered result.
+
+**Key concepts:**
+- Only chunks intersecting the viewport are considered for rendering
+- Each chunk tracks whether its content is "dirty" (needs redraw)
+- Static content renders once, then the cached texture is reused
+
+### Dirty Flag Propagation
+
+When layer content changes, only affected chunks are marked dirty:
+
+1. `layer.set((x, y), value)` marks the containing chunk as dirty
+2. On next render, dirty chunks redraw to their RenderTexture
+3. Clean chunks simply blit their cached texture
+
+This means a 1000x1000 grid with one changing cell redraws only one chunk, not 1,000,000 cells.
+
+---
+
+## Render Pipeline Stages
+
+### Stage 1: Viewport Calculation
+
+Calculate which chunks and cells are visible based on camera position, zoom, and grid dimensions.
+
+**Key properties:**
+- `center` - Camera position in pixel coordinates (Vector)
+- `zoom` - Scale factor (1.0 = normal, 2.0 = 2x magnification)
+- `size` - Viewport dimensions in screen pixels
+
+### Stage 2: Below-Entity Layers
+
+For each layer with `z_index < 0`, sorted by z_index:
+1. Determine which chunks intersect viewport
+2. For each visible chunk:
+   - If dirty: redraw layer content to chunk's RenderTexture
+   - Draw chunk's cached texture to output
+
+### Stage 3: Entity Rendering
+
+Entities render at the z=0 boundary:
+1. Iterate entity collection
+2. Cull entities outside viewport bounds
+3. Draw visible entity sprites at interpolated positions
+
+### Stage 4: Above-Entity Layers
+
+For each layer with `z_index >= 0`, sorted by z_index:
+- Same chunk-based rendering as Stage 2
+- These layers appear as overlays (fog, highlights, UI elements)
+
+### Stage 5: Final Compositing
+
+All rendered content is drawn to the window.
+
+---
+
+## Creating and Managing Layers
+
+### Standalone Layer Objects
+
+Layers are created as standalone objects, then attached to grids:
+
+```python
+grid = mcrfpy.Grid(grid_size=(50, 50), pos=(0, 0), size=(800, 600), layers=[])
+
+# Create layers as standalone objects
+background = mcrfpy.ColorLayer(name="background", z_index=-2)
+grid.add_layer(background)
+
+terrain = mcrfpy.TileLayer(name="terrain", z_index=-1, texture=tileset)
+grid.add_layer(terrain)
+
+# Overlay above entities (z_index >= 0)
+fog = mcrfpy.ColorLayer(name="fog", z_index=1)
+grid.add_layer(fog)
+```
+
+### Passing Layers at Construction
+
+You can also pass layers during Grid construction:
+
+```python
+bg = mcrfpy.ColorLayer(name="background", z_index=-2)
+tiles = mcrfpy.TileLayer(name="terrain", z_index=-1, texture=tileset)
+fog = mcrfpy.ColorLayer(name="fog", z_index=1)
+
+grid = mcrfpy.Grid(
+    grid_size=(50, 50),
+    pos=(0, 0),
+    size=(800, 600),
+    layers=[bg, tiles, fog]
+)
+```
+
+### Accessing Layers
+
+```python
+# By name
+fog_layer = grid.layer("fog")
+
+# All layers (returns tuple)
+all_layers = grid.layers
+print(f"Grid has {len(all_layers)} layers")
+```
+
+### Removing Layers
+
+```python
+grid.remove_layer(fog_layer)
+```
+
+---
+
+## Layer Operations
+
+### ColorLayer
+
+```python
+cl = mcrfpy.ColorLayer(name="highlights", z_index=1)
+grid.add_layer(cl)
+
+# Fill all cells with one color
+cl.fill(mcrfpy.Color(0, 0, 0, 255))
+
+# Set individual cell
+cl.set((5, 5), mcrfpy.Color(255, 0, 0, 128))
+
+# Read cell value
+color = cl.at((5, 5))
+print(f"Color: ({color.r}, {color.g}, {color.b}, {color.a})")
+```
+
+### TileLayer
+
+```python
+tl = mcrfpy.TileLayer(name="terrain", z_index=-1, texture=tileset)
+grid.add_layer(tl)
+
+# Set tile sprite index
+tl.set((5, 5), 42)
+
+# Read tile index
+idx = tl.at((5, 5))
+
+# Fill all cells
+tl.fill(0)  # All floor tiles
+```
+
+### Layer Properties
+
+```python
+layer = grid.layer("fog")
+
+# Visibility toggle
+layer.visible = False  # Hide layer
+layer.visible = True   # Show layer
+
+# Z-index (render order)
+layer.z_index = 2  # Move to front
+
+# Grid dimensions (read-only)
+w, h = layer.grid_size
+```
+
+---
+
+## Performance Characteristics
+
+**Static Grids:**
+- Near-zero CPU cost after initial render
+- Cached chunk textures reused frame-to-frame
+- Only viewport calculation and texture blitting
+
+**Dynamic Grids:**
+- Cost proportional to number of dirty chunks
+- Single-cell changes affect only one chunk
+- Bulk operations should batch changes before render
+
+**Large Grids:**
+- 1000x1000+ grids render efficiently
+- Only visible chunks processed
+- Memory scales with grid size (chunk textures)
+
+---
+
+## FOV Overlay Pattern
+
+The most common overlay pattern is fog of war using a ColorLayer:
+
+```python
+grid = mcrfpy.Grid(grid_size=(50, 50), pos=(0, 0), size=(800, 600), layers=[])
+
+# Background and terrain layers (below entities)
+bg = mcrfpy.ColorLayer(name="bg", z_index=-2)
+grid.add_layer(bg)
+bg.fill(mcrfpy.Color(20, 20, 30, 255))
+
+# Fog overlay (above entities, z_index >= 0)
+fog = mcrfpy.ColorLayer(name="fog", z_index=1)
+grid.add_layer(fog)
+fog.fill(mcrfpy.Color(0, 0, 0, 255))
+
+# Make cells traversable
+for x in range(50):
+    for y in range(50):
+        grid.at(x, y).transparent = True
+        grid.at(x, y).walkable = True
+
+# After computing FOV, update fog
+grid.compute_fov((25, 25), radius=10)
+w, h = grid.grid_size
+for x in range(w):
+    for y in range(h):
+        if grid.is_in_fov((x, y)):
+            fog.set((x, y), mcrfpy.Color(0, 0, 0, 0))    # Transparent
+        else:
+            fog.set((x, y), mcrfpy.Color(0, 0, 0, 192))  # Dimmed
+```
+
+---
+
+## Multiple Overlay Layers
+
+Pre-create multiple overlay layers and toggle between them:
+
+```python
+grid = mcrfpy.Grid(grid_size=(50, 50), pos=(0, 0), size=(800, 600), layers=[])
+
+highlight = mcrfpy.ColorLayer(name="highlight", z_index=1)
+danger = mcrfpy.ColorLayer(name="danger", z_index=2)
+fog = mcrfpy.ColorLayer(name="fog", z_index=3)
+grid.add_layer(highlight)
+grid.add_layer(danger)
+grid.add_layer(fog)
+
+def show_danger_zones():
+    highlight.visible = False
+    danger.visible = True
+    fog.visible = False
+
+def show_fog_of_war():
+    highlight.visible = False
+    danger.visible = False
+    fog.visible = True
+```
+
+---
+
+## Recreating Legacy Three-Layer Rendering
+
+The old system rendered: background color, tile sprite, FOV overlay. Here's the modern equivalent:
+
+```python
+grid = mcrfpy.Grid(
+    grid_size=(50, 50),
+    pos=(100, 100),
+    size=(400, 400),
+    layers=[]
+)
+
+# Layer 1: Background colors (z=-2, behind everything)
+background = mcrfpy.ColorLayer(name="background", z_index=-2)
+grid.add_layer(background)
+background.fill(mcrfpy.Color(20, 20, 30, 255))
+
+# Layer 2: Tile sprites (z=-1, above background, below entities)
+tiles = mcrfpy.TileLayer(name="tiles", z_index=-1, texture=tileset)
+grid.add_layer(tiles)
+
+# Layer 3: FOV overlay (z=+1, above entities)
+fog = mcrfpy.ColorLayer(name="fog", z_index=1)
+grid.add_layer(fog)
+
+# Populate layers
+for x in range(50):
+    for y in range(50):
+        tiles.set((x, y), calculate_tile_index(x, y))
+```
+
+---
+
+## Common Issues
+
+### Issue: Layer Changes Don't Appear
+
+**Cause:** Use layer methods (`set()`, `fill()`) which automatically mark chunks dirty.
+
+### Issue: Overlay Appears Behind Entities
+
+**Cause:** Layer z_index is negative.
+
+**Fix:** Use `z_index >= 0` for overlays:
+```python
+overlay = mcrfpy.ColorLayer(name="overlay", z_index=1)  # Not z_index=-1
+```
+
+### Issue: Performance Degrades with Many Changes
+
+**Cause:** Each `set()` call marks a chunk dirty; scattered changes mean many chunk redraws.
+
+**Fix:** For bulk updates, use `fill()` for uniform values:
+```python
+# Single operation - efficient
+layer.fill(mcrfpy.Color(0, 0, 0, 0))
+
+# Many individual calls - slower but necessary for non-uniform data
+for x in range(100):
+    for y in range(100):
+        layer.set((x, y), compute_value(x, y))
+```

-## Architecture Overview
-
-### Layer-Based Rendering
-
-Grids render content through **layers** rather than per-cell properties. Each layer is either a `ColorLayer` (solid colors) or `TileLayer` (texture sprites).
-
-**Render order is determined by z_index:**
-- Layers with `z_index < 0` render **below** entities
-- Entities render at the z=0 boundary
-- Layers with `z_index >= 0` render **above** entities (overlays)
-
-Within each group, lower z_index values render first (behind higher values).
-
-```
-z_index: -3    -2    -1    0    +1    +2
-         ↓     ↓     ↓     ↓     ↓     ↓
-       [background] [tiles] [ENTITIES] [fog] [UI overlay]
-```
-
-**Implementation:** See `UIGrid::render()` which iterates layers in z_index order, inserting entity rendering at the 0 boundary.
-
-### Chunk-Based Caching
-
-Large grids are divided into **chunks** (regions of cells). Each chunk maintains its own `sf::RenderTexture` that caches the rendered result.
-
-**Key concepts:**
-- Chunk size is implementation-defined (currently ~256 cells per dimension)
-- Only chunks intersecting the viewport are considered for rendering
-- Each chunk tracks whether its content is "dirty" (needs redraw)
-- Static content renders once, then the cached texture is reused
-
-**Implementation:** See `UIGrid::renderChunk()` for chunk texture management.
-
-### Dirty Flag Propagation
-
-When layer content changes, only affected chunks are marked dirty:
-
-1. `layer.set(x, y, value)` marks the containing chunk as dirty
-2. On next render, dirty chunks redraw to their RenderTexture
-3. Clean chunks simply blit their cached texture
-
-This means a 1000x1000 grid with one changing cell redraws only ~1 chunk, not 1,000,000 cells.
-
-**Implementation:** Dirty flags propagate through `UIGrid::markDirty()` and are checked in `UIGrid::render()`.
-
----
-
-## Render Pipeline Stages
-
-### Stage 1: Viewport Calculation
-
-Calculate which chunks and cells are visible based on camera position, zoom, and grid dimensions.
-
-**Key properties:**
-- `center` / `center_x`, `center_y` - Camera position in pixel coordinates (within grid space)
-- `zoom` - Scale factor (1.0 = normal, 2.0 = 2x magnification)
-- `size` - Viewport dimensions in screen pixels
-
-**Implementation:** Viewport bounds calculated at start of `UIGrid::render()`.
-
-### Stage 2: Below-Entity Layers
-
-For each layer with `z_index < 0`, sorted by z_index:
-1. Determine which chunks intersect viewport
-2. For each visible chunk:
-   - If dirty: redraw layer content to chunk's RenderTexture
-   - Draw chunk's cached texture to output
-
-### Stage 3: Entity Rendering
-
-Entities render at the z=0 boundary:
-1. Iterate entity collection
-2. Cull entities outside viewport bounds
-3. Draw visible entity sprites at interpolated positions
-
-**Note:** Entity culling is currently O(n). SpatialHash optimization planned in [#115](../issues/115).
-
-### Stage 4: Above-Entity Layers
-
-For each layer with `z_index >= 0`, sorted by z_index:
-- Same chunk-based rendering as Stage 2
-- These layers appear as overlays (fog, highlights, UI elements)
-
-### Stage 5: Final Compositing
-
-All rendered content exists in the grid's output RenderTexture, which is drawn to the window in a single operation.

-- Near-zero CPU cost after initial render
-- Cached chunk textures reused frame-to-frame

-

-- Only visible chunks processed
-- Memory scales with grid size (chunk textures)
-
-**Profiling:** Use `mcrfpy.getMetrics()` or the F3 overlay to see render times. See [[Performance-and-Profiling]].
-
----
-
-## FOV and Perspective System (In Transition)
-
-**Current Status:** The FOV computation (`compute_fov()`, `is_in_fov()`) works correctly for pathfinding and visibility queries. However, the automatic fog-of-war overlay system is **not currently connected** to the new layer architecture.
-
-**What works:**
-- `grid.compute_fov(x, y, radius)` - Computes which cells are visible
-- `grid.is_in_fov(x, y)` - Queries visibility of a specific cell
-- Pathfinding uses walkable/transparent properties correctly
-
-**What's in transition:**
-- Per-entity perspective (`UIGridPointState`) not yet exposed to Python
-- Automatic fog overlay rendering disconnected from layer system
-- Batch FOV data access being designed ([#113 discussion](../issues/113))
-
-**Current workaround - Manual fog layer:**
-
-```python
-# Create a fog overlay layer (positive z_index = above entities)
-fog_layer = grid.add_layer("color", z_index=1)
-
-# After computing FOV, update fog colors
-grid.compute_fov(player.grid_x, player.grid_y, radius=10)
-
-for x in range(grid.grid_x):
-    for y in range(grid.grid_y):
-        if not grid.is_in_fov(x, y):
-            # Dim color for non-visible cells
-            fog_layer.set(x, y, mcrfpy.Color(0, 0, 0, 192))
-        else:
-            # Transparent for visible cells
-            fog_layer.set(x, y, mcrfpy.Color(0, 0, 0, 0))
-```
-
-**Limitation:** This O(n²) iteration is inefficient for large grids. Batch operations ([#113](../issues/113)) will address this with patterns like `cells_in_radius()` iterators.
-
----
-
-## Layer Techniques
-
-### Multiple Overlay Layers
-
-You can pre-create multiple overlay layers and toggle between them:
-
-```python
-# Create several overlay options
-highlight_layer = grid.add_layer("color", z_index=1)
-danger_layer = grid.add_layer("color", z_index=2)
-fog_layer = grid.add_layer("color", z_index=3)
-
-# Populate each with different data...
-# highlight_layer shows selected cells
-# danger_layer shows enemy threat zones
-# fog_layer shows visibility
-
-# Toggle visibility to switch which overlay shows
-def show_danger_zones():
-    highlight_layer.visible = False
-    danger_layer.visible = True
-    fog_layer.visible = False
-
-def show_fog_of_war():
-    highlight_layer.visible = False
-    danger_layer.visible = False
-    fog_layer.visible = True
-```
-
-### Z-Index Reordering
-
-Change layer order at runtime by modifying z_index:
-
-```python
-# Bring a layer to front
-important_layer.z_index = 100
-
-# Send a layer behind entities
-background_layer.z_index = -10
-```
-
-**Note:** Changing z_index marks the layer dirty, triggering re-render of affected chunks.
-
-### Constructor `layers={}` Limitations
-
-The `layers={}` constructor argument is convenient but limited:
-
-```python
-# This creates layers, but ALL get negative z_index (below entities)
-grid = mcrfpy.Grid(
-    grid_size=(50, 50),
-    layers={"ground": "color", "terrain": "tile", "overlay": "color"}
-)
-# Result: ground=-3, terrain=-2, overlay=-1 (all below entities!)
-```
-
-**For overlays above entities, use `add_layer()` explicitly:**
-
-```python
-grid = mcrfpy.Grid(grid_size=(50, 50), layers={})
-ground = grid.add_layer("color", z_index=-2)
-terrain = grid.add_layer("tile", z_index=-1)
-overlay = grid.add_layer("color", z_index=1)  # Above entities!
-```
-
----
-
-## Migration from Legacy API
-
-Prior to the layer system, grids had built-in per-cell rendering via `UIGridPoint` properties. Here's how to recreate that behavior:
-
-### Legacy Pattern (Pre-November 2025)
-
-```python
-# OLD API (no longer works):
-grid = mcrfpy.Grid(50, 50, 16, 16)
-cell = grid.at(x, y)
-cell.tilesprite = 42        # Sprite index
-cell.color = (255, 0, 0)    # Background color
-```
-
-### Equivalent Modern Pattern
-
-```python
-# NEW API - explicit layers:
-grid = mcrfpy.Grid(grid_size=(50, 50), pos=(0, 0), size=(400, 400))
-
-# Grid creates a default TileLayer; access it:
-tile_layer = grid.layers[0]
-tile_layer.set(x, y, 42)    # Sprite index
-
-# For background colors, add a ColorLayer behind tiles:
-color_layer = grid.add_layer("color", z_index=-2)  # Behind default tile layer
-color_layer.set(x, y, mcrfpy.Color(255, 0, 0))
-```
-
-### Recreating Old Three-Layer Rendering
-
-The legacy system rendered: background color → tile sprite → FOV overlay.
-
-```python
-# Create grid with no default layers
-grid = mcrfpy.Grid(
-    grid_size=(50, 50),
-    pos=(100, 100),
-    size=(400, 400),
-    texture=tileset,
-    layers={}
-)
-
-# Layer 1: Background colors (z=-2, behind everything)
-background = grid.add_layer("color", z_index=-2)
-
-# Layer 2: Tile sprites (z=-1, above background, below entities)
-tiles = grid.add_layer("tile", z_index=-1, texture=tileset)
-
-# Layer 3: FOV overlay (z=+1, above entities)
-fog = grid.add_layer("color", z_index=1)
-
-# Now populate layers as needed
-background.fill(mcrfpy.Color(20, 20, 30))  # Dark blue background
-
-for x in range(50):
-    for y in range(50):
-        tiles.set(x, y, calculate_tile_index(x, y))
-
-# FOV overlay updated after compute_fov() calls
-```
-

-
-## Common Issues
-
-### Issue: Layer Changes Don't Appear
-
-**Cause:** Layer content changed but chunk not marked dirty.
-
-**Fix:** Use layer methods (`set()`, `fill()`) which automatically mark dirty. Direct property manipulation may bypass dirty flagging.
-
-### Issue: Overlay Appears Behind Entities
-
-**Cause:** Layer z_index is negative.
-
-**Fix:** Use `z_index >= 0` for overlays:
-```python
-overlay = grid.add_layer("color", z_index=1)  # Not z_index=-1
-```
-
-### Issue: Performance Degrades with Many Changes
-
-**Cause:** Each `set()` call can mark a chunk dirty; many scattered changes = many chunk redraws.
-
-**Fix:** Batch logically-related changes. For bulk updates, consider:
-```python
-# Less efficient: 10,000 individual calls
-for x in range(100):
-    for y in range(100):
-        layer.set(x, y, value)
-
-# More efficient when available: bulk fill
-layer.fill(mcrfpy.Color(0, 0, 0))  # Single operation
-```
-
-Batch operations API ([#113](../issues/113)) will provide more patterns.

-## API Quick Reference
-
-**Grid Properties:**
-- `center`, `center_x`, `center_y` - Camera position (pixels in grid space)
-- `zoom` - Scale factor
-- `layers` - List of layer objects, sorted by z_index
-- `fill_color` - Grid background (behind all layers)
-
-**Grid Methods:**
-- `add_layer(type, z_index, texture)` - Create new layer
-- `remove_layer(layer)` - Remove a layer
-
-**Layer Properties:**
-- `z_index` - Render order
-- `visible` - Show/hide layer
-- `grid_size` - Dimensions (read-only)
-
-**Layer Methods:**
-- `set(x, y, value)` - Set cell (color or sprite index)
-- `at(x, y)` - Get cell value
-- `fill(value)` - Fill all cells
