Cache-bust v=54 -> v=55 across index.html and sfxbank.js, bump the game
version to 0.8.0, document the HD Remaster setting in gameplay.md and the
changelog, and extend the smoke suite with 4x sheet-geometry bounds checks,
HD loader fallback URL assertions, and toggle persistence/reload checks.
218 stills + 24 sheets generated by tools/hd_assets.py at quality 90,
~220MB total. Loaded only when HD Remaster is enabled; standard PNGs
remain the default and the per-sprite fallback.
draw_sprites.py renderers take scale/smooth/src_dir/out_dir keywords with
SD-identical defaults (verified pixel-for-pixel against the committed
sheets); smooth swaps NEAREST for LANCZOS/BICUBIC. tools/hd_assets.py
derives the 4x WebP tier from assets/raw sources: flood-key, crop,
margin/fit/center without palette quantization, then renders 4x sheets
through a temp PNG bridge.
Sprites.load() serves assets/hd/<name>.webp in HD mode and falls back once
to the SD PNG per sprite; sheet frame sizes derive from sheet geometry
(width/8 for actor and legs sheets, height for the one-row death strip) so
both tiers address correctly.
G.hdRemaster persisted in localStorage (meatslicer_hd_remaster), toggled
from the title screen via H key or the bottom-left tag; activation reloads
so the asset tier and canvas resolution swap at boot. draw() applies a
uniform hdScale() transform, the room-layer cache renders at render scale,
and image smoothing follows the tier.
