<!--
src/features/settings/SettingsView.svelte — thin component.
Loads settings via the injected SettingsApi (GET /api/settings), routes every
field edit through the pure `updateField` reducer, and saves via PUT
/api/settings. A live `previewPath` shows where a file would land under the
current template. Pure view-model (tokens, isDirty, previewPath) lives in
logic.ts. No business logic here — only load/save/edit wiring.
