/* ──────────────────────────────────────────────────────────────────────────────
   TumbleTracker user manual — stylesheet for manual/admin/ and manual/staff/.

   The first three blocks (Reset & Base, Layout, Nav, Buttons, Footer) are copied
   VERBATIM from landing/index.html's inline <style> (lines 17-105 and 269-288,
   dedented) so the manual's header, footer, type and colours are the same as the
   marketing site. Change them there first, then re-copy — never diverge.
   Everything below "Manual layout" belongs to the manual only.
