/* Punctive — pre-launch page. Azure Field brand, per design/Punctive-Brand-Handoff/BRAND-SPEC.md.
   Contrast law (locked): azure #2E7FE0 never carries body-size text — white/navy on azure is
   display-scale (or ≥large-bold) only; text-scale azure on white is #1E63C4; long-form reading
   lives on white or navy. Two-blue rhythm: azure → white → navy → white → azure. */
