    Segmented control (#2137) — track + equal-footprint segments. The selected
    state is a single `--active` class so an optional Stimulus controller can
    toggle it as one unit. Values mirror the DS tab tokens (tab-bg-group /
    tab-item-active / tab-item-hover) but are inlined with `@variant theme-dark`
    because `@apply`-ing a custom utility drops its dark override. The near-black
    dark track (alpha-black-700) is what makes the gray-700 selected pill read —
    the bespoke controls used a too-light `container-inset` track, hence the
    audit's "selected pill invisible on dark." Focus = neutral outline (matches
    the canonical focus ring; inlined until that token lands on main).

    Horizontally scrollable table wrapper (#2137). `overflow-x: auto` so wide
    tables scroll instead of clipping (the LLM-usage table was `overflow-hidden`
    and pushed columns off-screen) or wrapping money mid-digit. The pure-CSS
    "scroll shadow" gives the missing affordance: the cover gradients
    (`--table-scroll-bg`, default container-inset) scroll WITH the content
    (`background-attachment: local`) and hide the fixed shadow gradients at the
    edges, so a soft edge-shadow only appears when there is more to scroll.
    Theme-aware via `--color-shadow`. Set `--table-scroll-bg` to match the wrapper.
