/**
 * Fonts offered in the slide editor's text-format picker.
 *
 * Every entry is a real web font: Inter via `next/font` (`app/layout.tsx`),
 * the rest via `@fontsource` packages loaded in `app/editor-fonts.ts`.
 * `@fontsource` `unicode-range`-subsets the CJK faces, so they download lazily
 * per glyph range — a picked font actually renders.
 *
 * Adding a font: install its `@fontsource` package, import the weight CSS in
 * `app/editor-fonts.ts`, then add an entry here whose `value` matches the
 * package's `@font-face` family name.
