An app installed as a PWA, and a mobile browser, colour their bar from <meta name="theme-color">, which the package left alone: the bar kept the server's one colour whatever theme the visitor chose. With the new `theme.meta` option (off by default), <x-theme-script> sets the content of every theme-color meta without a `media` attribute to the resolved theme's surface, from the scheme data and for the profile in <html data-scheme>, adding one to <head> when the page has none. A MutationObserver on <html> follows every later change of data-theme or data-scheme: $store.theme's set() and toggle(), an OS change while `system`, a profile preview, an application's own script. wire:navigate's head merge puts the next page's server-rendered meta in place, so it is painted again as the page is swapped in and on livewire:navigated. Turned off, the script is byte-for-byte what it was. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01RHoXZSHc8gGpZjFmA5fPc2
