   site.css — the shared chrome: fonts, design tokens, base elements, and the
   nav + footer that must look identical on every page.

   Every page links this FIRST, then adds its own page-specific <style> block,
   so page rules can override these. Do not copy nav or footer rules into a
   page — that is exactly the drift this file exists to prevent.

   Tree left of the wordmark, tagline stacked beneath it. The mark is a PNG
   because the handoff ships no SVG master; tools/make-tree-marks.py derives
   every variant from images/tree-mark-source.png, so recolouring the tree (a
   pending brand decision) is a one-line change there rather than a hunt
   through the image folder.

   The dark-ground footer gets a true white file, not a CSS filter — the brief
   rules the filter out for production, and it would also invert the amber dot.
