   Home page — "settlement terminal" direction.

   Loads after style.css. Everything new is namespaced `hp-` so it
   cannot collide with the shared component styles; only the design
   tokens are shared. Section rhythm is handled by .hp-section here
   rather than the inline padding overrides the old page used.

   One gap value governs the page: sections carry their space on the
   bottom only, so every section-to-section transition is exactly
   --gap. The hero is the one exception — it ends in a rule, and a
   rule needs air on both sides, so it gets --gap split either side
   of the line instead of a full --gap twice. */
