-/**
- * THE SETTINGS PAGE (thin settings wave, 2026-09-19): one column, section
- * blocks in fixed order — General, Agent, Appearance, Graph, Keyboard —
- * over the versioned delta record at GET /api/settings, written per
- * section through PUT /api/settings/[section] (replace-whole).
- *
- * Thin by owner decision: simple controls, real read/write, the point is
- * a WORKING validation surface that exercises the whole settings schema —
- * not the designed settings app. Polish lives in a later wave.
- *
- * The chat section (new-session defaults) is deliberately NOT here
- * (owner decision): its controls live on the /chat/new surface; two
- * editors for one value is a drift bug. The auth/provider-keys page is
- * deliberately absent (needs auth.json plumbing that doesn't exist).
