/* ================================================================
   typography.css  –  Compliance Checker
   Reusable text scale (Figma node 6:71).
   Apply these as utility classes on any element; pair with .muted /
   .uppercase helpers when the design calls for it.

   Order matters: the scale classes set colour to var(--ae-black),
   the helpers below them override colour / transform on top.

/* === HEADINGS (NexaBold) ======================================
   Each rung targets both the semantic tag AND a matching class, so
   a plain <h2> styles itself while a span or a mis-levelled heading
   (e.g. a <h3> that should look like an h4) can opt into a rung via
   class="h4". Class selectors outrank element selectors, so the
   class wins when both are present. */
