/**
* The Appearance + Graph sections (thin settings wave).
*
* Appearance controls resolve against the factory in the provider; writes
* PUT the whole appearance section and hand the delta back so the CSS
* variables move IMMEDIATELY (the section's whole point — it must DO
* something). Hex inputs commit on blur/Enter; the background derives the
* raised/accent/edge palette in code (components/settings/appearance.tsx).
* Mode is dark-only this wave: control rendered DISABLED with a note — the
* light palette is the design wave's work, and a lying control is worse
* than an honest disabled one.
*
* Graph graying (owner, 2026-09-20) follows the graph viewer's render-panel
* convention: the whole row dims when a parent is off (stored values
* persist but resolve inert — the switch shows stored, the dim effective).
*
* Reading font (appearance wave, 2026-09-26, owner ruling): a searchable
* dropdown of the user's INSTALLED fonts (FontMenuList over model-menu's
* machine) fed by window.queryLocalFonts() in the desktop shell — the
* enumeration is click-bound (the API requires user activation), deduped
* to unique families, the factory family excluded (the DEFAULT row is
* it). In a plain dev browser the API is absent → a small curated list
* + a footer that says exactly that — never a fabricated system list.
* The custom-family input inside the menu is the manual escape path.
* Empty/unset keeps meaning Source Sans 3.
*
* Emphasis inks (same wave): the factory tokens default to the regular
* text color now (globals.css); the rows' empty-state labels say "same
* as text".
