Kbd

A styled `<kbd>`: `inline-flex`, `h-5`, `min-w-5`, centred, `px-1`, `rounded-sm`, `bg-muted` with `text-muted-foreground` and a `border-border` edge, `font-sans text-xs font-medium` so keys match UI text rather than monospace. `[&_svg:not([class*='size-'])]:size-3` sizes icon children unless they set a size. Tooltip adaptation uses an ancestor arbitrary variant, `[[data-slot=tooltip-content]_&]:…`, keyed on this library's tooltip `data-slot`, so no context is needed. Compared with the source: a border is added, the dark-mode-only tooltip tint is folded into one translucent tint that works on the tooltip's lit-key surface (`bg-linear-to-b from-key-top to-key-bottom`, `text-primary-foreground`) in both themes, and `KbdGroup` is typed as `<kbd>`.

**Pebble (2026-11-03).** The key is now a pebble cap rather than a bordered chip: `raised` is `bg-card` with `ring-1 ring-hairline`, an inset `0 -1px 0 var(--hairline)` bottom edge plus `--elevation-xs`, and `inset-shadow-highlight` on top (`dark:bg-muted` so the cap still separates from a dark card). `lit` reuses the lit-key recipe (`from-key-top to-key-bottom`, `ring-key-edge`, `--key-shine`) at `--elevation-xs`. `flat` keeps the old muted look with no edge. Corners are `rounded-[5px]`, type is 11 px `tabular-nums` so digits line up in shortcut columns, and a `variant`/`size` pair is exposed with `data-variant`. The tooltip override now also clears the gradient, ring tint, shadow and inset highlight (`bg-none`, `shadow-none`, `inset-shadow-none`) and keys take the tooltip's ink: `bg-primary-foreground/15`, `text-primary-foreground`, `ring-primary-foreground/25`, and repeats the tint under `dark:` so it beats the raised cap's dark background. Colour and shadow transitions are dropped under `motion-reduce`.
