Dialog

Radix `Dialog` provides portal, focus trap, scroll lock, `aria-hidden` on siblings and
dismissal. The scrim is `bg-black/50` rather than a `foreground` tint because foreground
turns light in dark mode and would brighten the page. The panel is centred with
`top-1/2 left-1/2 -translate-x-1/2 -translate-y-1/2`; Tailwind v4 writes these to the
CSS `translate` property, so the entry keyframes can animate `transform: scale()`
without overwriting the centring. Animations are arbitrary `animate-[...]` utilities
keyed on Radix's `data-state` and wrapped in `motion-safe:`; Radix's Presence waits for
`animationend` before unmounting, so the exit runs. Keyframes ship in the registry item
`css` field: `dialog-fade-in/out` (opacity 0 to 1, 150 ms) and `dialog-zoom-in/out`
(opacity plus scale 0.96 to 1, 200 ms in / 150 ms out, ease-out in / ease-in out). The
surface uses `card`/`card-foreground` and gets a `CanvasText` border in forced colors.

**Pebble (2026-11-03).** The panel is now a Pebble raised object: `rounded-2xl`,
`ring-1 ring-hairline`, `shadow-raised-lg` and `inset-shadow-highlight`, with `gap-5`
and `p-6`. The scrim is the `--scrim` token (`bg-scrim`: black at 40%, 60% dark) with a 2 px backdrop blur. Timing
moved to the motion tokens: the zoom-in runs `--motion-slow` on `--motion-enter`, every
exit `--motion-fast` on `--motion-exit`, the scrim fade `--motion-base`. Reduced motion
swaps the zoom for the existing `dialog-fade-in` keyframe instead of nothing, so no new
keyframes ship. A `size` prop (`sm`/`md`/`lg`, default `lg`) maps to the `sm:max-w-*`
width and is mirrored as `data-size`. The title is 16 px semibold with -0.01em tracking;
the description is `text-pretty` with relaxed leading. The demo is a project card whose
real triggers (Rename, a danger-tinted Delete) open a rename form with a live slug and a
type-to-confirm delete whose danger key stays disabled until the slug matches.
