   GEOpetra design system — TERS theme (restrained)
   ---------------------------------------------------------------------
   Brand chrome (nav, wordmark, eyebrow, footer) carries the GEOpetra
   look. The "meat" of the app — analysis cards, tables, forms, results —
   keeps Bootstrap's clean default surfaces and uses the brand palette
   only as ACCENTS (primary buttons, links, active states, focus rings).

   Tokens mirror GEOpetra_website/DESIGN_SYSTEM.md — keep them in sync.
   This file is for the interactive app only; PDF/print templates are
   standalone and intentionally unaffected.
