/*
Executive Briefings — application styles.

Palette matches the generated PDF so the interface and its output read as one
system. Contrast is checked against WCAG 2.2 AA: 4.5:1 for normal text, 3:1 for
large text and interactive boundaries.

Neuro-inclusive defaults, per the house standard:
  - text is #1a2230 rather than pure black, on #fafbfc rather than pure white,
    because maximum contrast causes visual fatigue over long reading
  - no decorative animation by default
  - every transition is disabled under prefers-reduced-motion
  - focus is always visible; outline is never removed without a replacement
