 * The trigger is 44px, matching `Input` and `Button`, because it is the same
 * kind of thing a thumb aims at. Stock shadcn ships it at 36px, which is where
 * Settings' timezone select and every filter built on this primitive were
 * failing PIG's own touch rule — not because a call site chose 36px, but
 * because nobody had chosen anything.
 *
 * The rest of the treatment is `Input`'s exactly: 12px radius because it is a
 * control, `bg-surface` because a transparent field has no edge on a tinted
 * canvas, and focus read as the border changing rather than an extra outline.
