   PRODUCT PAGES — shared rules (g-Platform, g-Space, g-Viewer)
   2026 design system — Geomage Website (www.geomage.com)

   Loaded by every product template ALONGSIDE main.css. Everything the three
   product pages share but that is not a design-system component lives here:

     · .hero-title      — the <p> the SSR layer demotes the product H1 to
     · .stats .container— full-bleed stats band (replaces a concept inline style)
     · .mod__topics     — deep-URL links inside a module card
     · .panel__sub--stack — small gap left by the components
     · .topic-detail    — the per-topic panel seo.py injects at <!-- TOPIC_DETAIL -->

   Page-unique rules go in pages/<page>.css, never here.
   ═══════════════════════════════════════════════════════════════════════════ */

/* ── HERO TITLE, DEMOTED ─────────────────────────────────────────────────────
   On a deep URL the topic fragment owns the page's single <h1>, so the SSR
   layer (backend/app/routes/seo.py) demotes the hero heading to a paragraph.
   Both spellings of that swap are supported: a tag-only replacement keeps
   .hero__title (styled by components/hero.css); the alternative rewrites the
   class to .hero-title, which this rule styles identically. */

/* The phone-width `.hero__eyebrow { white-space: normal }` override that used to
   live here (and in pages/home.css) now sits with its root cause, next to
   `.eyebrow { white-space: nowrap }` in components/section-head.css. */

/* ── STATS BAND ──────────────────────────────────────────────────────────────
   The blue stats band's grid spans the full container width — the concept
   zeroes the container padding with an inline style; this replaces it. */
.stats .container { padding: 0; }

/* ── MODULE-CARD TOPIC LINKS ─────────────────────────────────────────────────
   Every module card links to the deep URLs it covers: the first (primary) is
   the card's own page, the rest are the sibling topics grouped into that card.
   data-topic on each anchor is the SSR module-switcher's hook. */

   TOPIC DETAIL
   The panel the SSR layer injects at <!-- TOPIC_DETAIL --> (directly under the
   module grid) when a deep URL is requested. Visually it is an expanded,
   permanently highlighted module card: white surface, orange border and top
   rule, the same radius and rhythm as .mod.
