/* Bench page palette — adapted from euchre_server/src/bench.rs:899-916,
   re-tuned for a four-tier hierarchy on blog post pages:
     1. site title  (header h1)            — small chrome bar
     2. post title  (article > h1)         — page anchor, largest
     3. section     (article h2 = `#`)     — major section break
     4. subsection  (article h3 = `##`)    — minor section
   Body markdown headings are shifted +1 by the renderer so post body
   content never produces an <h1>. */
