Reapply the existing Retrom Web/checkpoint patches onto upstream
0a36f376270087a229bf268591582af4760607fe(60 new upstream commits), preserving linear ancestry on the new maintenance baseline. Fix WebGL texture/surface format initialization that caused black rendering, preserve GMLReal angle precision during checkpoint restoration, and reject unsupported active physics or disabled drawing state.Validation: source contract, 11 Web host tests, native checkpoint/gamepad/lazy-read regressions, clean Wasm build/release validation, and actual Chrome Loritta rendering regression (black before the fix, rendered pixels afterward). Retrom PFB Undertale gameplay, public checkpoint and fresh-browser restoration/input passed. Two earlier intermittent cold-browser observations (visual/input anomaly and startup timeout) remain unattributed; retries, further fresh-browser recovery and old/new-core cold-store probes passed. These observations are retained in the Retrom acceptance report.
Promote with a fast-forward after CI to preserve the verified linear source history. No games or private evidence are committed.
