/**
 * actionIcons — menu/toolbar ACTION key → inline SVG icon mapping.
 *
 * The sibling of `lib/fileIcons.ts`, for the other half of the problem: that
 * module draws what a row IS (a folder, a sheet, an archive), this one draws
 * what a row DOES (open, rename, move to trash).
 *
 * Why it exists: the action rows used to carry emoji (`↗ 👁 ⬇ 🗑 …`). Emoji are
 * not one icon set — they are a dozen sets, rendered by whatever font the OS
 * happens to ship, at whatever weight and colour that font's designer chose.
 * Two rows of the same menu could come out flat-grey and full-colour, one
 * hairline and one bold, and none of them matched the file glyphs drawn four
 * pixels to the left. A stroked set on `currentColor` gives the menu one voice
 * and lets the row's own colour reach the icon — which is how the destructive
 * entry, and only the destructive entry, comes out red.
 *
 * Conventions are `fileIcons.ts`'s, deliberately: static strings (so `v-html`
 * is injecting markup this file wrote, never user input), one cache, 24×24
 * viewBox, 1.6 stroke, round caps/joins, `currentColor`.
 *
 * Adding a key: draw it here. Nothing else has to change — the renderers ask
 * for the icon by the action's own key, so a new action gets its icon the
 * moment its glyph lands in GLYPHS, and an action with no glyph renders
 * nothing (the caller falls back to whatever `icon` string it was handed, so
 * an embedder's custom emoji still shows).
