/* ==========================================================================
   Quantara Tech Services — Design tokens
   Palette pulled directly from the brand mark: Navy #14144A (ink),
   Gold #F0A824 (primary accent — the "Q" mark's fill), a deeper gold for
   hover states, Paper #F8F7F4 (warm-neutral surface, not stark white),
   Slate #4B5170 (muted text).
   Type: Sora (display/headings) paired with Inter (body); IBM Plex Mono
   for stats and the eyebrow labels, echoing a technical, precise register.
   Signature: the logo's own motif — two overlapping squares (navy behind,
   gold in front) — recurs as a structural device: section markers, the
   card corner-accent, and the stat-block divider. A small four-point
   "sparkle" glyph (lifted straight from the mark) punctuates key moments
   instead of a generic icon set.
