/* ============================================================
   SimMedAi static pages — one stylesheet for every prerendered page under public/
   (compare, examprep, features, magnets). 2026-10-17 modern pass + colour pass.

   Theme: the SAME theme as the signed-in app, light and night. The surface, text,
   border, brand and accent values below are copied literally from src/styles/base.css
   (html[data-theme="light"] / html[data-theme="dark"]); night follows
   prefers-color-scheme. The decorative layer (hue palette, shimmer, micro-motion)
   mirrors src/styles/public-site.css with the same names and values.

   Generated pages get this file from their generator template (gen_*_pages.py);
   hand-written pages link it directly. Content lives in the HTML; this file is only
   the look, so a restyle never touches what answer engines read.
   Contrast: text colours are the app's audited tokens (>= 4.5:1 on every surface).
   All motion stops under prefers-reduced-motion.
