/* ==========================================================================
   workwithzaki.com — portfolio site for Zaki.
   Single page, monochrome, no JS, no frameworks. The visual language is
   intentionally close to usemizan.app so the two sites read as the same
   designer's work, but the typography is the inverse — DM Serif Display
   for the hero headline (Inter on Mizan) and Inter for the wordmark
   (Serif on Mizan). Cousins, not twins.
