   PLAYBOOK — shared reading surface (AX system, 2026-09-16)
   Loaded via BaseLayout additionalCss by /playbook/, /playbook/[chapter]/ and
   /playbook/industry/[industry]/. Holds ONLY what those three templates share:

     1. the warm off-white ground and the reading-progress bar
     2. the 760px article column: parallax hero + fact caption, the rail TOC,
        numbered sections, the .ax-pb-body prose rhythm (same values as the
        blog's .ax-bd-body), the citable sentence, serving line, related links
     3. the pb-* furniture classes that the chapter/industry data HTML hard-codes
        (tables, bars, callouts, sample-reply quotes, checklists, phases)

   Page-only layout (the hub's chapter cards and trade row) lives in that
   page's own <style is:global>. No element is styled in both places.

   Light on purpose: these are long-form reads (~89% light, approved by Ram
   2026-08-17). Ground #fbfaf8, ink #1c1917. Orange #ff9200 is a fill or rule
   only; orange TEXT on this ground is var(--ax-otext) #9c4f00.

   Loads BEFORE ax.css, so every prose rule is prefixed .ax-pb to out-rank the
   .ax scope resets (.ax p { margin: 0 }, .ax ul { list-style: none }).
