   BUILD : CSS-2026-07-31-A
   FILE  : /assets/acmpro.css

   This is the site's chrome: design tokens, the two-strip header, the
   footer, buttons, section headings and the card/box system. Every page
   links it and then adds ONLY what is genuinely unique to that page.

   LINK IT LIKE THIS
     root pages   <link rel="stylesheet" href="assets/acmpro.css">
     /lab/ /kit/  <link rel="stylesheet" href="../assets/acmpro.css">
     /bench/      <link rel="stylesheet" href="../assets/acmpro.css">

   RULE OF THUMB
     If a rule would look right on more than one page, it belongs here.
     If it only makes sense on one page, leave it in that page's <style>.

   WHAT IS DELIBERATELY *NOT* HERE
     - the homepage rotating hero (.hl*)      — homepage only
     - the Insights hub knowledge graph       — /lab/index.html only
     - long-form article typography (.art-*)  — article pages only
     Those stay inline on their own pages.
