   Daddy Mi portal — stylesheet C "Ink & Light" 水墨之光 (LIVE)
   Boss ruling 2026-11-09: candidate C design + Track A calligraphy.
   Palette and typography are candidate C's, verbatim: pale
   rice-paper ground, deep indigo ink, gold used as LIGHT — one
   soft glow behind the hero, never metal trim. Noto Serif SC/TC
   text, EB Garamond italic Latin accents. The rules are mapped
   onto the live portal's structure (portal-src/build.py template);
   page structure and content never change with the stylesheet.
   No dark-mode rules anywhere: the design is light-locked, so the
   indigo ink can never land on a dark background.
