/* ============================================================
   VITALS ACADEMY — design tokens
   Palette:  --navy (deep clinical navy) / --red (signal red, CTA only)
             --paper (warm-white background) / --ink (body text)
   Type:     Display  — 'Space Grotesk'  (confident, technical, echoes the
                          angular EKG mark in the logo)
             Body     — 'Inter'           (clean, highly legible at small size)
             Readout  — 'IBM Plex Mono'   (used ONLY for eyebrows, stats,
                          timestamps — reads like a vitals-monitor readout)
   Signature: an EKG pulse-line motif (drawn from the brand's own logo)
              threads through section dividers and draws itself in on load.
