/* ExpertInvo palette: NAVY (spec 236, boards 12-17, picked by Ben 2026-10-28). The ONE colour source: every
   page links this file and no component carries a literal colour. Navy with restraint: --base paints the bands
   (closing band, footer) and --header the sticky header; reading stays on --paper/--page; --spark (cyan) only on --base; amber
   --action is the one warm thing (Book) with --on-action navy (white on amber is 2.0:1). The build fails if a
   text/background role pair drops under AA (build_website.py CONTRAST_PAIRS). Previous palette, for a switch
   back: page F4F2ED ink 1A1A18 soft 5A5852 line DCD8D0 faint 716D65 ink2 14532D accent/action/spark B45309
