The corpus catches up with the wave — sixteen colors, a symbol browser, a hideable sidebar, and the context menu's four groups

Amendments the worktree agents owed but could not write: 03's palette
counts and the symbol full-browser reversal (CoreGlyphs-derived catalog),
05's sidebar visibility ruling, 11's Show Sidebar row and the card
context-menu row reshaped to the four-group structure with its two
flagged gaps (style pre-focus, the disabled Navigation pair).
