/* ==========================================================================
   amiraliyaghouti.com — homepage, v4

   v4: nothing scrolls inside itself. Code windows and the project card are
   sized to their longest content by the script; on a phone code wraps rather
   than scrolls. Résumé and Contact are actions, not footnotes. The Persian and
   Arabic hero code is written in Persian and Arabic and laid out right-to-left.

   Direction: editorial on an OLED ground. The page is one flat surface with
   hairline rules and a numbered mono label opening each section — not a stack
   of identical cards. Boxes are reserved for things that are actually items
   (a project, a package, an offer). Type does the hierarchy: a geometric
   display face for titles, a monospace face for every label, number and
   file name, the system sans for reading. One accent, cyan, and it means one
   thing: a measured number or the primary action.

   No !important. Logical properties throughout, so RTL is free.
