New tooling in tests/tools/screenshots/ (TypeScript via tsx):
- compare.ts: one pixelmatch engine (AA-excluded), connected-component
"where to look" boxes, old|new+boxes|heatmap triptych, per-engine floors.
- promote.ts: churn-free updater — overwrite a baseline only when decoded
pixels differ beyond the floor, copying CI bytes verbatim (no re-encode
churn); pulls a CI run via `gh run download` or a local --from dir.
- post-discord.ts: always-on CI-on-main report (SHA + e2e status + the
track-only runtime-perf table), then screenshot triptychs, batched +
size-capped + flood-collapsed + 429-aware.
- perf-report.ts: perf table with Δ vs the previous main run (via gh).
- changelog.ts: no-build git-history baseline differ (Discord trigger B).
- noise.ts / gen-manifest.ts: calibration + manifest generation.
CI wiring:
- wasm-build.yml: post-test step runs the gate + report on the already-
produced test-results (no extra build); report-only (continue-on-error),
posts only on push to main, inert without DISCORD_WEBHOOK_URL.
- ci-ubicloud.yml: secrets: inherit (pass the webhook through).
- screenshot-changelog.yml: ~30s no-build changelog on baseline changes.
screenshot-manifest.json: canonical 354-name set + best-effort engine tags
(313 chromium-swiftshader / 41 firefox-llvmpipe).
Normalize scale:'device'->'css' across 18 spec files (no-op at CI DSF=1)
so committed baselines are uniformly css-scaled.
Design: CI's Linux render is the single source of truth; no pinned
container (accept rare env drift -> re-promote); dev commits via promote.
Replaces the byte-cmp compare-screenshots.sh + file-size-proxy
update-baseline-screenshots.sh (kept for now until the first re-baseline).

Builds KiCad's 3D viewer for the browser (opt in with BUILD_3D_VIEWER=ON) and
wires up the legacy-GL emulation it needs.
- build-kicad-target.sh / docker/build.sh: BUILD_3D_VIEWER →
-DKICAD_BUILD_3D_VIEWER_WASM=ON + -sLEGACY_GL_EMULATION + the GL js-library.
- wasm/shims/gl_immediate_shim.js: display-list emulation (record/replay board
layers), fixed-function + GLU stubs, throw-guards for unsupported pnames, and
per-context GLImmediate init for the viewer's SECOND WebGL context.
- tests/kicad/3d-viewer.spec.ts + utils/pcbnew-ready.ts: open View → 3D Viewer.
- bumps the kicad submodule (EMSCRIPTEN-guarded GL changes).
WIP: the viewer window + UI render and geometry draws (glError=0x0), but the
board is not yet visibly rendered — GLImmediate's FFP shader program isn't
linked on the viewer's 2nd WebGL context. Full status + next steps in
features/feat/add-3d-view/notes.md.
