- app.html: inline blocking script resolves the theme from localStorage
(or prefers-color-scheme) and sets data-theme on <html> before first
paint, eliminating the dark→light transition users saw when the light
theme was selected.
- +layout.svelte: hydrate sidebar collapsed state and expanded nav groups
synchronously in their $state initializers instead of inside onMount,
so the sidebar no longer snaps from expanded→collapsed and groups no
longer slide open after mount.
- +layout.svelte: keep the global provider-filter row rendered while
providersCache.fetchedAt === 0, so the row doesn't pop in mid-paint
and push the nav down once the cache resolves.
