/* ============================================================
   Your Solutions Architect
   Near-black industrial ground, Barlow Condensed uppercase display,
   two-channel cyan and coral accent, 14px rounded panels - tuned up-market for
   a professional services audience: calmer accents, more air, an
   architecture drawing in place of machine artwork.
   Note: the inherited --text-dimmer (#5f6a8a) fails WCAG AA at 3.6:1,
   so this site uses #7882a2 (4.56:1 on panel) for the same role.

  /* Graphite ground, two-channel instrument accent. Cyan carries structure and
     intent - display type, CTAs, rules, active states. Coral carries the reading
     layer - links, eyebrows, kind labels, warnings. Cool frame, warm annotation,
     the way a drawing is marked up. Chosen over a single accent so the page does
     not read as one acid color on black.
     Every value verified against all four surfaces at WCAG AA. */
