/* ==========================================================================
   AM Consulting Group — shared design system

   v6 palette: same as Parallel AI's (parallel-ai-consulting.vercel.app).
     - --primary/--ink is dark navy, --background/--surface a warm cream,
       --accent a warm amber — taken directly from Parallel AI's own
       design system rather than differentiated from it.
     - --highlight is a brighter gold, used for the headline highlighter-
       mark, eyebrow-on-dark, and the decorative squiggle/photo-halo touches
       added in an earlier round — kept in the same warm family.
     - --link carries a supporting blue — present as a secondary accent (the
       2nd color in card-grid rotations), not the loudest color on the page.
     - --secondary (dark navy) — still used for dark surfaces and the 3rd
       rotation color.
   Spacing/layout convention (--pad-h / --section-py / --max-w responsive
   token pattern) modeled on sophrosynesystems.org's Section/Container
   approach.
