* [LocalEventThemeToggle]; `null` everywhere else. [AppTheme] reads [fonts] to swap [AppTypography]; the app bar reads

* [accent] for its wash and [palette] for its brand rule. The event info sheet and branding icon are driven separately

* by [LocalEventBranding][org.meshtastic.core.ui.util.LocalEventBranding] so they stay available even when opted out.

*

* @param accent the edition's primary — calm enough to sit behind title text as a low-alpha wash.

* @param highlight the edition's loud detail color, for small marks that need to pop rather than recede.

* @param palette every brand color the edition publishes, in authored order; empty when it publishes none.
