Breadcrumb

Plain semantic HTML: `nav > ol > li`, with separators as their own `li` elements so the list wraps cleanly with `flex flex-wrap` and a gap (`gap-1.5`, `sm:gap-2`). `BreadcrumbLink` swaps the `<a>` for Radix `Slot.Root` under `asChild`, so `data-slot`, classes and props merge onto a framework link. Icons are inline 16-unit SVGs drawn with `currentColor` (chevron stroke, three filled dots) so they follow the text colour; the separator sizes its SVG child with `[&>svg]:size-3.5`. No client hooks, so no `"use client"`; the parts render in server components. Compared with the source: lucide icons replaced by inline SVGs, landmark label capitalised and overridable, `role="link"`/`aria-disabled` dropped from the page, the ellipsis label made audible and configurable, link focus ring and hover underline added.

**Pebble (2026-11-03).** Links became small `h-7 px-1.5 rounded-md` hit targets with a `bg-muted` hover tint instead of an underline, a felt press (`active:scale-[0.97]`, off under `motion-reduce`) and the loud `ring-2 ring-ring ring-offset-2` focus ring. The page matches their height and padding so the trail does not shift. Type is 13 px; items keep `gap-1.5` for icon children (sized `3.5`), the list tightens to `gap-0.5` since each link now carries its own padding, and separators fade to `text-muted-foreground/60` with a slimmer chevron. `BreadcrumbList` gains `variant="raised"` (with `data-variant`), a card pebble: `bg-card ring-1 ring-hairline shadow-raised-xs inset-shadow-highlight`. Still no client hooks.
