`[2026-07-07]` **Affect-derived tooltips (`v0.20.5`) + transparent squirrel vendored + v0.20.0–.5 PUSHED to origin (operator-authorized).** Native `title` hints on all 6 affect-derived cells (samples/updated/baseline P·A/drift Δv/volatility — each with meaning + Tier-1-vs-Tier-3 availability). Committed the transparent full-res brand mark at `docs/design/ratatoskr-mark.png` (1024², alpha; the bg-removed source the inlined favicon derives from — reproducible via the documented ImageMagick corner floodfill). The web-UI redesign arc (v0.20.0 Claude Design console → .1 sparkline-overflow+tooltips → .2 context-injection → .3 squirrel brand/favicon → .4 SVG sparklines+3D cube → .5 derived tooltips) is now all on `origin/main`.
