/* ══════════════════════════════════════════════════════════
   PixelBlocker+ site: the PixelBlocker family look (plan 3.6, 5.1)
   The colours, fonts, notches and spacing come from pb_tokens.css, which is
   GENERATED from pb_design/pb_tokens.json (python3 pb_design/generate.py).
   Every page links pb_tokens.css first, then this file. Never copy a colour
   value in here by hand: read a --pb-* variable.

   The short names below (--red, --bg-card, --font-mono and the rest) are the
   names the pages' own <style> blocks already read. Each one points at a
   PixelBlocker token, so a page reads the family look without a rewrite.
