pub fn use_theme_provider(theme: Option<ThemeConfig>) -> Signal<String>Expand description
Provide the CurrentTheme context and apply the persisted theme on mount.
Reads the stored preference from localStorage (falling back to the config’s
default theme), sets data-theme on <html>, and keeps the returned signal
in sync. Called by DocsLayout/BlogLayout; call it yourself when you
render kit components (e.g. ThemeToggle) outside
those layouts, e.g. in a landing-page navbar.
