…e loop is seamless assets/feature-noderoom-hero.gif was rendered before 341fd20 guarded the step-0 cross-fade (Defect D2), so frames 0..3 fade up from the white letterbox (mean luminance 139/115/79/55 vs about 20) and every loop restarts on a flash. Frames 0..3 are removed at the byte level; frame 4 becomes a full-canvas frame in the same global palette; frames 5..187 are untouched. Pixel-exact new[i] == old[i+4], delays and loop flag preserved. 188 -> 184 frames. Evidence manifest re-pinned (sha256 + bytes + appended limitation); projection and receipt regenerated with `node scripts/featureclip-evidence.mjs project --write`. Gate script, CI and thresholds untouched. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Removes the grey/white fade-in lead frames from the README hero GIF (README.md line 28 embeds it; the site page https://homenshum.github.io/featureclipstudio/ shows it too) so each loop restarts on the real first frame instead of a flash. (Flash-free restart, not a literal seamless join: the last scene still cuts back to the landing page, per Codex review.) Path and name unchanged; README untouched.
Method: byte-level frame drop (same technique as NodeAgent PR #22). Frames 0..3 are removed. Because the GIF is delta-optimized, original frame 4 only stored a partial rectangle over frame 3's canvas; it is replaced by the full composited canvas of original frame 4, encoded against the ORIGINAL global palette (every pixel maps back to a palette index, no quantization), with its original delay. Frames 5..187 are copied verbatim.
compare.py: composited new[i] == before[i+4] pixel-exact for all 184 frames, delays equal, loop flag equal, PASS.ffmpeg -v error -i new.gif -f null -decodes with no errors.Cause: Defect D2 (probe-opening-frame.mjs lines 1-14). The renderer cross-fades each step in over the previous one; step 0 had nothing to fade from, so it ramped up from the
#fffletterbox. The renderer was fixed by 341fd20 (2026-08-13, src/Walkthrough.jsx line 186opacity: prevImg ? fadeIn : 1), but this GIF was committed 2026-08-04 (45c8d8b) and never re-rendered; PR #25 only re-encoded it. The generator is not re-run here (no new captures, and a re-render would not keep frames 4..187 pixel-identical), so only the shipped asset is trimmed.Evidence re-pin, same method as PR #25: manifest artifact
