   Color:
     --ink:      #1B2B34  (near-black slate, body text)
     --deep:     #0E4F52  (deep teal — trust, primary)
     --deep-2:   #0A3638  (darker teal — hover/active)
     --pulse:    #E4572E  (EKG-line coral — used ONLY for the
                 waveform + focus/alert states, never decoration)
     --paper:    #F7F8F6  (page background, soft clinical white)
     --card:     #FFFFFF
     --line:     #DDE3E1  (hairline borders)
     --muted:    #5B6B6C
     --good:     #2F7D5C
   Type:
     Display/headers: IBM Plex Serif 700 (a steady, medical-
       journal serif — signals care & credibility, not flashy)
     Body/UI: IBM Plex Sans (legible at small sizes on phones,
       tested for accessibility)
   Signature element:
     A single continuous EKG waveform is the connective tissue
     of the whole flow — it runs along the progress bar and
     "beats" once when a step completes. It is the only place
     motion happens.
