   Generated markup lives between the SAG-NAV markers in every .html file.
   Edit build-nav.py (markup) or this file (styles). Never hand-edit the
   injected block: the next build-nav.py run overwrites it.

   Everything is prefixed .sag- so it cannot collide with the per-page
   styles that already exist in the 15 pages.

/* The header is site chrome, not page content, so it does NOT inherit the
   per-page --accent. Nine pages define six different accents (level-2 is
   periwinkle, workflows green, claude-office blue, linkedin-feed-tracker
   LinkedIn blue) and a CTA that recolors per page reads as six sites, not
   one. Page accents stay in the body, where they answer "which guide am I
   in." These values are literal for the same reason. */
