M3 § Chips, Accessibility asks that a row which overflows horizontally carry a
visible affordance; `<x-chip-set scroll>` faded its edges and left it there
(plan step 24, audit docs/audits/m3-alignment/inputs.md § Missing). Where the
pointer is fine, and so there is no swipe to reach for, a button now sits over
each fading edge and scrolls the row by most of its width. They are pointer
affordances only — no tab stops, since the arrow keys already walk every chip —
and the row's scroll padding grows on a fine pointer so a chip the keyboard
reaches clears the buttons as well as the fade. The scroller became a ref,
because the buttons stand outside it.
