Design system mandates Lucide, not Material. Foundation before the
mechanical Icons.* sweep:
- pubspec: add flutter_lucide ^1.11.0
- shared/widgets/lucide_heart.dart: LucideHeart renders the verified
lucide-icons/lucide heart path as outline (stroke) or filled, via
flutter_svg, tinted by color — Lucide ships no filled heart, so the
liked state fills the same Lucide silhouette (user-chosen approach)
- like_button: use LucideHeart instead of Icons.favorite/_border
- notification drawables re-derived from the verbatim Lucide heart
path (border = stroke, filled = fill); separators spaced for
Android pathData
Unit 2 (mechanical Icons.* -> LucideIcons.* sweep) follows once this
is CI-green. pubspec.lock regenerated by CI.
