/* ══════════════════════════════════════════════════════════════════════════════════════════
   Knowledge pages — the hub, a section, Plan Guides (all areas, one area, one plan), an entry.

   A hierarchy, so every page shows the next level down as titles and lets the reader choose:
   sections → topics → questions, or areas → plans → questions. Questions are the collapsible
   .kn-qd from knowledge-ui.css. Phone first: body text at 17px with generous line height, short
   measure, no images, nothing that moves or pops up. Colours are the site's tokens; an area's
   accent arrives as the three custom properties AreaPalette writes (--as-rgb, --as-ink,
   --as-ink-dark), the same ones the activity selector uses.
