/* ═══ Polish layer · invariants ═══
   One rule per concern so every page behaves the same.
   I1 Spacing: 3 rhythms only. Inside a component 8 to 24px. Between components --space-fluid-md. Between sections --section-y.
   I2 Color: ink and ground carry the page. Navy appears only as one mark per view: eyebrow square, active nav line, focus ring, list number.
   I3 Radius: pill for controls, 16px for media and cards, 8px for inputs and labels. Nothing else.
   I4 Lines: 1px hairlines only, and only where they group content (nav, FAQ, table, stat top). Sections separate by space.
   I5 Motion: color and border 160ms, surfaces 320ms, movement 640ms on --ease-out. Hover lifts 2px at most. No bounce.
   I6 Focus: one ring everywhere, 2px navy at 3px offset. */
