/* =====================================================================
   BLOG — gaya ala 21st.dev: grid-pattern hero, badge shimmer, kartu
   "spotlight" dengan border glow mengikuti kursor, TOC sticky, prose rapi.
   Memakai token dari main.css (--red, --blue, --ink, --mut, --line, dst)
   sehingga otomatis ikut mode gelap.
