/* =========================================================
   WriteUpCafe — topic-v2.css (2026-11-15 topic page redesign)
   One page per topic, a tab per type. Scoped under .tv2.
   Written to design-system/design.md: dark hero (H1 gold 64/900), parchment body,
   H2 36/700 and H3 28/600 in copper-dark, DM Sans 600 card titles, copper eyebrows,
   40px pill buttons, tab-chip selection, palette colours only.
   Writeup cards (.ts-wcard), blog cards (.blog-card) and the sidebar (.ts-sc) keep
   their existing styles from app.css; type cards come from series-listing.css (.slv).
