Panels are a new kernel rendering tier between surfaces and block renderers, enabling composable companion views (e.g. notes panel inside chat). This version ships the plumbing layer: - Manifest validation for panels field (provider map + consumer array) - Soft-dep warning at install time for unresolved panel consumers - PanelMeta struct + resolvePanels() resolves consumers at surface load - window.__PANELS__ injected into base template - sw.panels SDK module (open/close/toggle/isOpen/isAvailable/list/active) - Lazy JS loading pipeline with module caching - 10 new tests (6 validation + 4 resolve) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
