livewire-material/tests/Browser/DatepickerTest.php

Andreas Reinhold / reiniandClaude Sonnet 5 d15312023b Move browser-test probes off Tailwind utility classes 
Plan step 38 (last batch), plan step 42's target for tests/: every
Tailwind utility class in a tests/Browser/*.php probe's Blade string
or Livewire component render() (~60 class attributes across 14 files)
becomes an inline style built from --md-sys-color-*/--md-sys-shape-*/
--md-sys-measurement-* tokens or a literal px value for an arbitrary
demo size — PickingTest's clip box, every probe's <body
class="bg-surface">, the grid/stack/row wrapper divs, the carousel
item's coloured filler. No test's assertions, selectors or expected
text change; these are layout containers around the components under
test, not anything a test reads.
