/* ════════════════════════════════════════════════════════════
   HABITAT PROFILE — shared structure ("the bones")
   Brygada 1918 + Outfit + DM Mono · ecotone palette = DEFAULT only

   This file owns LAYOUT and STRUCTURE for every habitat profile:
   hero, facts band, sections, keystone callout, layer timeline,
   life hub, plant-by-layer rows, story cards, neighbouring-habitat
   cards, footer, and responsive behaviour.

   PERSONALITY lives per page in css/habitats/[slug].css.
   Every colour here is read from a :root token (incl. the translucent
   accents, via *-rgb channel tokens). A habitat changes its whole
   look by overriding tokens — it should NEVER need to re-declare a
   component rule just to recolour it. The values below are the
   default (Woodland Edge / ecotone) theme; other habitats override.

   Loads after ../css/base.css and before the page's habitat CSS.
