   Haultin — Ghost theme styles
   ─────────────────────────────────────────────────────────────
   Built on the FORWARD design canon as adopted by the dashboard
   (dashboard/src/client/styles.css), not the older marketing CSS:

     · Petrona        — headings, wordmark, long-form reading, figures
     · Libre Franklin — body furniture, apparatus, labels, nav, meta
     · Spline Sans Mono — machine tokens only (used sparingly)

   Labels/kickers are sentence-case Libre Franklin with NO tracking
   and NO all-caps (canon update). Two surfaces only — parchment
   ground, parchment-soft panels. Hard corners, hairline rules.
