/* DirectorPM editorial design system (2026-09 redesign).
   Shared by the three redesigned hand-written pages: index.html, playbook/index.html,
   cheat-sheet.html. Loaded AFTER site.css so its skip-link / focus-ring overrides win,
   and BEFORE each page's inline <style> so page-specific rules win over this file.
   Hairline system: 1px rules only, border-radius 0 everywhere, no shadows. */
