   Palkan Marine — main.css
   Design direction: "Precision instrument"
   Cool hull-navy + brass, engineered type, Plimsoll load-line signature.

   Colour tokens below are defaults. config.json's "theme" block is injected
   by header.php as :root overrides AFTER this file, so the palette (and every
   color-mix derived from it) is editable from config / the future dashboard.

   CONTENTS
     1.  Design tokens (colour, type, spacing, layout, motion)
     2.  Reset / base elements
     3.  Layout helpers (container, section, eyebrow, lead, skip-link)
     4.  Signature — the load line (Plimsoll mark)
     5.  Buttons
     6.  Site header — topbar, brand
     7.  Primary navigation (progressive enhancement; .js + .is-open)
     8.  Hero / page-hero / dark band (section--ink)
     9.  Cards / grids
     10. Forms (+ contact extras: split, contact-list, alerts, map)
     11. Site footer
     12. FAQ (details/summary)
     13. Stats
     14. Utilities
     15. Reduced motion
