   Styles for [hud_stack] (inc/stack.php). Loaded only on singulars
   whose content actually contains the shortcode, so no other page
   pays for it. Delete this file + inc/stack.php + the enqueue block
   in functions.php to revert.

   Custom properties (--accent, --panel, --display, --mono ...) are
   declared on .hud in hud.css and inherit down to everything here,
   so this file must stay inside a .hud wrapper. page.php provides it.

/* The shortcode output sits inside .hud-entry__body, which caps at 76ch so
   ordinary prose stays readable. CSS cannot reach a parent, so inc/stack.php
