 * Phase Academy — common application shell + form/visual system (Phase 3 pilot).

 * Presentation only. This stylesheet never participates in any calculation.
 * Every rule is scoped under `.pa-shell-active` (set on <html> by app-shell.js)
 * so it can only affect applications that opt into the pilot.
 *
 * Target size: interactive controls are held at >= 44x44 CSS px with >= 8px
 * spacing to satisfy WCAG 2.2 SC 2.5.8 (Target Size, Minimum) with margin.
