/* web_clientes portal -- "Catalogo" theme (concept_09) :: per-page styles.
   ------------------------------------------------------------------
   Project detail, unit detail, and photo views. Mobile-first.
   Loaded AFTER portal.css, so it inherits every design token from
   portal.css :root (--font-display, --card, --border, --brass*,
   --badge-*-text, --shadow-card, --ring, etc.). The class contract
   from the previous theme is preserved verbatim; only the values
   change. Re-skinned from "Sala Verde" to the "Catalogo" editorial
   design language: ink surfaces, brass hairlines, Termina display
   numbers, tiny tracked uppercase eyebrow labels, catalogo chip
   pills. New surfaces are darker, so AA contrast ratios only improve.

   Mobile-first structure: unprefixed rules target phones; enhance
   upward via min-width:576 / 768 / 992. KPI row 2->3->5 cols;
   .thumbs grid 96px->140px min. Touch targets stay >= 44px.
