/* ==========================================================================
   /aux-go — the آکس‌گو introduction page.
   Loaded only on this page, through @push('headHook'), so nothing here costs
   the rest of the site a byte.

   The page borrows the app's own material palette rather than the theme's,
   because the subject is the app: ink is an oiled workbench, the light surface
   is a raw melamine face, and the one saturated colour is the AUX red.

   One rule governs the motion. The hero animates the cut plan -- the thing the
   product makes -- filling a sheet part by part, once, on load. Nothing else on
   the page moves without being asked. And nothing that is a Largest
   Contentful Paint candidate animates its opacity: an element at opacity 0 is
   not painted, so fading the headline in would postpone LCP by exactly the
   animation delay. See memory/project.md, where that was learned the hard way
   on the homepage.
