/* ad-hints.css — the AI ad-hint strip: machine-proposed windows, shown but never actionable.
 *
 * Styled deliberately unlike .marker-segment (hatched and muted, never a solid colour) so a hint
 * cannot be mistaken for a confirmed human annotation. There is no edit affordance, no drag handle
 * and no overlay: the only interaction a bar has is a click that navigates to its first frame.
 *
 * Palette comes from the :root custom properties in style.css — design-system.css is not loaded by
 * the discover page. Square corners match the house style.
