/*
 * <x-badge>: M3's small and large badges, and the library's status label.
 *
 * BadgeTokens (androidx Compose Material 3, Apache-2.0): the small badge is a 6px dot
 * (`data-md-dot`), the large badge 16px tall and at least 16px wide with 4px either side of a
 * `label-small` count in tabular figures, both fully round and `error` by default. A floating
 * badge sits on M3's anchor geometry at the top-end corner of its `position: relative` parent: the
 * dot flush in the corner, the count 2px above it with its start 12px in from the parent's end.
 *
 * The status label (`data-md-variant`) is not an M3 badge: 24px tall, small corner, 8px either
 * side, 4px between an icon and its word, `label-medium`. `tonal` draws it in the colour's
 * container, `solid` in the colour itself, `outline` as a 1px `outline` edge around
 * `on-surface-variant` text — `outline` rather than `outline-variant`, because M3 asks a badge for
 * 3:1 against what is behind it and `outline-variant` is the decorative role dividers use.
 *
 * `data-md-color` picks the pair of roles; `neutral` has no hue of its own (`on-surface-variant`
 * and `surface`, or `surface-container-high` behind `on-surface-variant` text), and `plain` sets
 * no colour at all, so the caller's CSS paints it.
