+| `RibbonButton.svelte` | `big` / `small` / `icon`, plus the split button. Hover paints the **icon box**, not the whole button. A big label wraps onto two lines at a 78px cap and its caret rides beside the icon, so a three-word label costs width instead of a third row |
 | `RibbonMenu.svelte` | The dropdown panel; its look is global CSS, since its rows come from a caller's snippet |
 | `Icon.svelte`, `icons.ts` | Path data on a 16-unit canvas. `pinnedStroke(size)` holds the painted stroke at ~1.5px on large glyphs and ~1.1px on small ones, so 14px and 28px icons read as one family |
