TL;DR
Blade templates that branch @if($isTailwind) ... @elseif($isBootstrap) for CSS classes don't scale. Adding a Flux theme meant a third branch in every file.
I moved all class strings into one static map (ThemeStyles) and gave Blades a single seam: themeClasses('key'). Themes now override keys, not re-implement templates.
Kept it closure-free so it survives config:cache, and guarded every migration with characterization tests that assert the rendered HTML is byte-for-byte unchanged.
This is from the public cleaniquecoders/laravel-livewire-tables v4 fork.
