/* —— Hero ——
   Pulse's hero predates and inspired the shared `.layer-hero` primitive
   (site.css §"Layer hero", DESIGN.md §5) every other page now uses. It stays
   on its own `.pulse-hero`/`.pulse-hero--textured` classes rather than
   `.layer-hero` because it does genuinely more: full 100vh sizing, an <h1>
   inside the band, a scroll-cue and "Enter briefing" CTA, and chapter-scroll
   choreography none of the single-viewport layer pages need. Rules that are
   byte-for-byte identical to the shared primitive (`.hero-stat-value`,
   `briefing-rise`) are still kept local here on purpose — `.hero-stat`'s
   spacing and `.hero-stat-label`'s type differ deliberately from the shared
   version (short caption vs. full sentence) and aren't worth forcing
   together at the cost of a markup change to a page that's already correct.
   `briefing-rise` itself was deduplicated: the canonical copy now lives in
   site.css and this file no longer redeclares it. */
