   LIVING BRAND · SCAFFOLD.CSS
   ===============================================================================
   The shared page shell for a "living-styleguide-*" reference page: the reset,
   the .mast header, the .jobrow section heading, and the .el demo+spec grid
   (live component on the left, explanation on the right). Extracted 2026-09-11
   after finding it duplicated near-verbatim across ~26 pages, with small
   accidental drift in a few spots (a 320px/330px grid-column split, a 52px/56px
   heading margin, a missing .spec background) that got normalized to one value
   as part of this extraction rather than left to keep drifting.

   Depends on colors-light.css (or colors-dark.css — either half of the
   swappable pair) being linked first. This file only supplies structure,
   never a color value directly, which is what lets a page swap its color
   file without touching this one.

   A page overrides any rule here by re-declaring the selector in its own
   <style> block, AFTER these two <link> tags — normal CSS cascade, no !important
   needed. living-styleguide-cards.html's mirrored .spec panel (border-right
   instead of border-left) and living-styleguide-illustration.html's slightly
   larger .spec padding are both handled this way: real, kept intentionally,
   not treated as drift to eliminate.

   NOT included here: .page{} (max-width genuinely varies 1160/1200/1240px by
   content need) and code{} background tinting (several pages give inline code
   their own accent tint) — both stay page-local on purpose.
