"""Responsive Design Cookbook - Layouts that survive aspect ratio changes
Interactive controls:
1: Landscape 16:9 (1280x720)
2: Desktop 4:3 (1024x768)
3: Ultrawide 21:9 (1260x540)
4: Portrait 9:16 (720x1280)
S: Cycle scaling modes (Fit / Stretch / Center)
ESC: Exit demo
This demo shows three approaches to resolution-independent layout:
APPROACH 1 - "Fit and forget" (scaling_mode="fit")
Design for one resolution. The engine scales and letterboxes.
Simplest. Works great when aspect ratio won't change.
APPROACH 2 - Alignment anchoring (align=TOP_RIGHT, margin=10)
Attach elements to edges/corners. The engine repositions them
when game_resolution changes. Good for HUD elements.
APPROACH 3 - Layout function (compute positions from resolution)
Write a function that takes (width, height) and places everything.
Most flexible. Required when layout structure must change
(e.g. sidebar becomes bottom bar in portrait mode).
The demo uses Approach 3 to build a game-like HUD that restructures
itself for landscape vs portrait orientations.

Regression test for issue #146: compute_fov() returns None
The compute_fov() method had O(n²) performance because it built a Python list
The compute_fov() method had O(n^2) performance because it built a Python list
of all visible cells by iterating the entire grid. The fix removes this
list-building and returns None instead. Users should use is_in_fov() to query
visibility.
