/* ════════════════════════════════════════════════════════════════════
   business-networking-common-ground-flyer — styles.css

   Design language: modern editorial / professional networking poster.
   Warm paper + deep ink + one confident cobalt accent. Instrument Serif
   (editorial serif) for display, Inter (clean sans) for body and UI.
   Inspired by the clean, typographic invitation cards used by premium
   online stationers: generous whitespace, hairline rules, small-caps
   labels, a monogram mark — no stock photography.

   Shell contract:
     - Default (no JS): normal stacked document flow.
     - html.shell-on (added by main.js): single-viewport 100dvh shell where
       only the active panel scrolls internally.
