Do not install Alpine separately; Livewire provides it.
+Importing the package's CSS replaces parts of Tailwind's theme with M3's, so some default utilities no longer compile. Breakpoints are the most visible: they are M3's window size classes and only those — `medium:` 600px, `expanded:` 840px, `large:` 1200px and `extra-large:` 1600px, with `max-medium:` and friends for "below", compact being everything under `medium`. Tailwind's `sm:`…`2xl:` are cleared, so an `sm:grid-cols-2` left over from another project compiles to nothing; rewrite it as `medium:grid-cols-2`. The same goes for the default radius, shadow, text-size, weight, leading, tracking and easing scales, which the M3 sets (`rounded-corner-*`, `shadow-elevation-*`, `type-*`, `ease-spatial-*`) replace. Scripts that need a window size class import `from()` / `upTo()` from the package's `resources/js/breakpoints.js` rather than writing their own media query.

### Layout
The theme script goes in `

- Elevation: `shadow-elevation-{1…5}` — for what floats over content, not for panels (a panel separates by its container tone).
- Motion: `ease-spatial-{fast|default|slow}` (position, size, shape; springs that overshoot) and `ease-effects-{fast|default|slow}` (colour, opacity, which never overshoot). Always pair an easing with its duration: `duration-(--md-sys-motion-spatial-fast-duration) ease-spatial-fast` — M3's published web durations, spatial 350/500/650 ms and effects 150/200/300 ms. `motion.scheme` in the config picks `expressive` (the default, with the bounce) or `standard` (minimal bounce), which the head script writes to `` and which swaps the three spatial springs; a component names a spring, never a scheme. Reduced motion zeroes every duration in both schemes.
- States: `state-layer` (M3's hover/focus/press overlay; makes the element `relative` and `isolate`), `focus-ring` (keyboard focus indicator), `link` (a link in running text).
+- Breakpoints are M3's window size classes, and only those: `medium:` 600px, `expanded:` 840px, `large:` 1200px, `extra-large:` 1600px, with `max-medium:` … for "below" (compact is below `medium`). Tailwind's `sm:`…`2xl:` are cleared — a `sm:` compiles to nothing — because 640px means nothing in M3. Scripts ask `resources/js/breakpoints.js` (`from('expanded')`, `upTo('medium')`) so a stylesheet and a script never disagree at the boundary pixel; a component's *own* width is a container query (`@md:`), which is a different thing.
- `dark:` follows the page's theme (`data-theme`), not the operating system.
- `x-figure` on an element holding one number counts it up on first appearance and on change.

Every component that meets the edge of the screen (app bar, navigation bar and rail, docked and placed toolbars, full-screen search, dialog and side sheet, bottom sheet, the skip link) keeps clear of a notch or home indicator through `var(--material-safe-top|bottom|left|right, env(safe-area-inset-…))`.
