/* ============================================================
   Shera Potka — sherapotka.github.io

   Register: chaptered scroll narrative, light base, one accent.
   Reference: /Users/sherabregu/Desktop/Wel (structure, type, motion).

   The accent is a deep red of her own, one degree off WelTel's
   #c8102e, so the site reads as her identity rather than an
   employer's brand.

   Two rules carried from Wel, deliberately, against the habits
   in Param:
     1. NO wide-tracked eyebrow. Wel's letter-spacing sits at
        0.2-0.3px. Tight, not airy.
     2. Instrument Serif is a scalpel, not the voice. It appears
        only on ONE accent word per headline. Headings themselves
        are Inter at -0.02em.
