<x-chip> renders data-md-chip with its type and its states and parts as
data-md-* attributes (elevated, disabled, selected, actionable, the
icon, check slot, avatar, action and remove button), and every colour,
size, target and transition moves into components/chip.css on tokens
(plan step 36). Icons take size 18; the filter checkbox is
md-visually-hidden. chips.js follows the renamed chip hooks.
A disabled filter chip drawn as a label no longer shows a hover state
layer, which M3 never gives a disabled control. Browser tests cover the
32px chip and the remove button's 48px target.
