Why: R4 spans ui (token scale) and frontend (icon set + restyle); the Dev repo advances pointers and the task record. Evidence: make test full suite green on this head (exit 0); headless journey on the real binary across both themes with zero console errors and zero leftover emoji glyphs. Impact: pure visual layer. Merge order: ui -> frontend -> this PR. Refs: proposal 2026-09-30-ui-redesign-and-auth.md (R4)
