/* ============================================================
   theaxes.fyi — essay light override.
   Linked AFTER each essay's own inline <style> so it wins.
   Flips the bespoke dark palettes (4 naming schemes) to the
   shared "graph notebook" light system + fonts, and styles the
   injected shared nav. The narration player (#nbar) stays dark —
   it now matches the homepage's docked audio bar.
