/* Workshop surfaces (student / facilitator / manager).
 *
 * Scoped to ``.hca-workshop`` so it works independently of the Tailwind CDN
 * already loaded by ``base.html``. Design tokens come from the workshop design
 * contract §6 (orange identity, blue secondary, readable contrast).
 *
 * Rules honoured here:
 *  - orange = identity / primary CTA, blue = secondary / informational;
 *  - all interactive controls >= 44px tall with a visible focus ring;
 *  - stacked (single column) on small screens;
 *  - deliberately no ``position: fixed`` anywhere -- nothing overlays content.
