/* Shared shell for the GitHub Pages sub-pages (how-it-works / pricing /
   blog). Same design language as the landing page: warm white, brand
   red accent, brand yellow highlights, soft borders, big confident type.

   IMPORTANT: pages must link this RELATIVELY (../_assets/site.css) —
   a leading-slash href resolves to sinhaankur.github.io/_assets/… and
   404s on the /WatchTower/ project path (that bug shipped once: the
   sub-pages rendered completely unstyled in production).

   The --wt-* token names are legacy (pages' local <style> blocks use
   them) — values are remapped to the current palette so page-local
   styles inherit the new look without touching every rule. */
