   Yiang Li — personal site stylesheet

   Brand palette (written as literals throughout to keep the cascade
   identical to the original; the dark theme in darkmode.css remaps them):
     #75140c  brand red   — links, accents, active nav, highlights
     #001527  ink         — headings
     #232b34  body ink    — body text, footer background
     #faf7f5  paper       — soft section background
     #ccc     line        — card / panel borders

   Section guide (jump with "==> "):
     ==> Base & typography        (body, headings, links, buttons)
     ==> Header / navigation
     ==> Home / welcome banner
     ==> Research & publications
     ==> Teaching
     ==> Footer
     ==> Responsive (see @media blocks near the end)

   Notes:
     - Self-hosted Avenir @font-face blocks were removed: the fonts/
       folder is absent and headings/body use Georgia. An unused (and
       invalid) Noto Sans SC @import was removed as well.
