/* Public Help centre: /help (topic grid) and /post/{id} (topic page).
 *
 * Dark theme on top of theme-dark.css (`.user-body--dark`); the header and
 * footer come from site.css. Layered surfaces rather than flat black, the
 * brand gold as the single accent, and a soft blue only in the background
 * aura. Mobile first.
 *
 * Fluid sizing: like the site header, every text size, space, control and
 * content width below is a `clamp()` that grows with the viewport width, from
 * a phone minimum to a wide-monitor maximum. The page therefore fills the
 * screen proportionally at every size instead of staying a narrow column in
 * the middle of a large monitor. The topic grid shares the header's side
 * gutter, so cards line up with the brand and the menu.
 *
 * Motion: entrance (fade + rise, staggered for cards), a slow drift of the
 * background aura, card lift on hover and a pointer spotlight driven by
 * help-page.js. Only transform and opacity are animated; everything stops
 * under prefers-reduced-motion and the page is complete without JavaScript.
