Plan step 36. <x-badge> renders data-md-badge with data-md-dot, data-md-variant (solid, tonal or outline, resolved in that order), data-md-color and data-md-floating; badge.css draws BadgeTokens' dot and count, the status label, each colour's pair of roles through custom properties, and M3's anchor geometry when floating. A plain badge sets no colour, so the caller's CSS paints it. NavigationBarTest (navigation group) asserts the dot by data-md-dot.

* <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.
