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.
- Bigger gore-red Minis (r10->14, sprite 32->48) with regenerated art
- Wider, walkable doorways: clear passage for open, teeth only when locked
- 500ms spawn telegraph so wave spawns no longer blindside the player
- Item stickiness ramps 10%/owned item (cap 50%) instead of flat 50%
- Title-screen Pressure Dial (-5..+5) tunes rise/relief; score x live pressure
- Vitals HUD: two-row hearts, half-container outlines, half-heart shield pips
- Readable 8-page field manual (bigger panel + fonts, implants split)
- HUD opacity slider in pause menu (boss bar + toasts stay opaque)
- Scrap Feed now has diminishing returns like Thick Hide
- Docs, cache-bust v37, and smoke coverage for all of the above
