/* Guisera — questions.
 *
 * The previous treatment was the stock SaaS accordion: every question in its own
 * rounded bordered card with a violet + / − on the right. It matched the
 * reference site closely enough to be a problem, and stacking twelve bordered
 * boxes reads as clutter rather than order.
 *
 * This is editorial instead of boxed:
 *   - hairline rules, no cards, so the page is a list and not a pile of chrome
 *   - a numbered index, which is what makes a long list feel organised
 *   - a thin chevron in slate, not a coloured plus
 *   - answers held to a ~66ch measure so long ones stay readable
 *   - on the FAQ page, a sticky category rail doing real navigation
 *
 * Built on <details>/<summary>, so it opens, closes and announces correctly with
 * no JavaScript. The scroll-spy in faq.js is decoration on top of that.
 *
 * Loaded after home.css and pages.css, which no longer carry any .h-faq rules.
