/* components/filter-chips.css — active-filter chips (components/filter-chips.js).
 *
 * Compact chips ("LONG ×  30m ×", brief §11) in a horizontal `overflow-x`
 * scroller: the row never widens the page (MOBILE_PLAN.md §2.8's scroll-x
 * pattern — components/scroll-x.js adds the edge fade when wrapped around
 * this row). The × button keeps a compact glyph and grows an invisible 44 px
 * hit area under `(pointer: coarse), (max-width: 767.98px)` (brief §6,
 * pattern 1), so the visuals do not change and the taps still land.
 *
 * Colour, type, spacing, radius and motion come only from tokens.css.
 * No literal colours anywhere here.

   The row grows to --hit-min only while it holds a chip (an empty row
   collapses to nothing) so the scroller — whose overflow-x:auto computes
   overflow-y to auto as well — does not clip the extension's hit area. The
   chip's trailing padding is half the hit area less the × button's half box,
   which keeps the whole extension inside the pill: the hit area can never
   widen the row's scroll width past the last chip. */
