Implement GJK (Gilbert-Johnson-Keerthi) overlap detection and EPA
(Expanding Polytope Algorithm) penetration resolution for arbitrary
convex collider pairs. Used as the fallback narrow phase for any
combination involving Capsule, while Sphere/Box specialized routines
are preserved for performance.

Add Capsule { radius, half_height } to the Collider enum, with AABB
computation and ray-vs-capsule intersection support. The capsule is
oriented along the Y axis (cylinder + two hemisphere caps).

Parse PNG files (RGB and RGBA, 8-bit) with full filter reconstruction
(None, Sub, Up, Average, Paeth). Uses the self-contained deflate
decompressor for IDAT chunk decompression.

Implement RFC 1951 Deflate decompression with zlib wrapper handling.
Supports stored blocks, fixed Huffman codes, and dynamic Huffman codes
with LZ77 back-reference decoding.

Add IMGUI HUD overlay showing HP, wave, score, and enemy count.
Display centered Game Over panel with final score and restart prompt.
Add procedural sine-wave audio clips for shooting (440Hz) and enemy
kills (220Hz) via voltex_audio. Player blinks white during invincibility.
Press R to restart after game over.

Projectiles destroy enemies on contact (radius check 0.55). Enemies
damage the player on contact with 1s invincibility window. Score +100
per kill. Game over when HP reaches 0. update() now returns FrameEvents
so the caller can trigger audio/visual feedback.

Red sphere enemies spawn at arena edges via a wave system that
escalates each round. Enemies use direct seek steering to chase
the player. Both shadow and color passes render enemies.

Left click fires small yellow sphere projectiles from the player toward
the mouse cursor position on the XZ plane. Includes fire cooldown (0.2s),
projectile lifetime (2.0s), and ray-plane intersection for mouse aiming.

Add blue sphere as the player with WASD movement on XZ plane,
clamped to arena bounds. Camera now tracks player position.
Pre-allocate dynamic UBO buffers for 100 entities to support
future enemies and projectiles.

reserved u8) and per-variant payload encoding. Includes 7 unit tests covering
all roundtrips and invalid-type error handling.

Implements SteeringAgent and five steering behaviors. truncate() clamps
force magnitude. follow_path() advances waypoints within waypoint_radius

Implements find_path() using A* over triangle adjacency with XZ heuristic.
Path starts at the given start point, passes through intermediate triangle
centers, and ends at the goal point. Returns None when points are outside
the mesh or no connection exists. 5 passing tests.

Lighting pass now renders to Rgba16Float HDR target. A 5-level bloom
mip chain (downsample with bright-extract threshold, then additive
upsample) feeds into an ACES tonemap pass that composites the final
LDR output to the swapchain surface. All resources resize correctly.
