/* Overlays (#3442, epic #3432 DS-8): popover / menu, tooltip (simple and
 * rich), modal, drawer and toast. Behavior (focus trap, Escape, outside
 * click, return focus, flip) is ds/overlays.ts. Tokens only.
 *
 * Buttons inside an overlay are the #3438 family (.btn .btn-primary /
 * .btn-secondary, sizes .btn-s/.btn-m/.btn-l); this file only places them.
 *
 * Proposed, not in Figma (designer questions on #3432): the scrim color and
 * blur, the simple tooltip, the toast's top-right placement, the drawer's
 * slide, and every duration below. Durations read #3443's motion tokens and
 * fall back to the values the issue gives until those land. */
