/* ==========================================================================
   VEDHAVERTEX - Passport Size & ID Photo Maker
   Design language: precision print production. The recurring visual motif
   is the corner "registration/crop mark" used on real cut sheets - it shows
   up in the eyebrow, the stepper, and the hero mock-up because it is the
   literal mechanism the product outputs (cutting guide ticks on the A4
   sheet), not a decorative flourish.
