/* Hallmark · v2.0.0 · redesign: full · scope: app · shape: app screen · theme: brand (Capgemini blue #0070AD, Plus Jakarta Sans), two schemes: Aurora light and Midnight dark (light-dark tokens, device default, user switch) · genre: modern-minimal (inferred)
 * waivers (owner decision, 3 Nov 2026, docs/UI-STANDARDS.md §5): expressive motion instead of state-only: a fresh start screen cascades in (320ms rises, 30ms apart); the glow blooms once (500ms) and then holds; the verdict badge overshoots; every one-off animation ends within 500ms (owner decision, 7 Nov 2026). Reduced motion stills all of it, delays included.
 * critique: the old start screen was a centred greeting over six identical cards; it is now a roster you scan like a team sheet, and a Team run reads as one rail of hand-offs.
 * signature: the Team relay rail: each specialist hands to the next on one line, the Reviewer's verdict in the Team header.
 * keeps: every id, class hook, handler and test selector; Capgemini blue and Plus Jakarta Sans; the agent colours. */
