Rewrite the carousel without Tailwind

Plan step 36 (containment group): <x-carousel>'s and <x-carousel-item>'s
class lists move into resources/css/components/carousel.css and
carousel-item.css, keyed on data-md-carousel (its value is the layout)
and the parts' data-md-carousel-* hooks (-probe, -scroller, -controls
with "auto"/"always", -previous/-next, -item, -surface, -content,
-label/-label-text). Every selector uses a `>` combinator rather than a
bare descendant one, because a carousel item can itself hold a nested
carousel whose own root would otherwise match its parent's layout
rules too (list.css already solves the same problem for segmented
list rows).

Behaviour is unchanged: resources/js/carousel.js (the keyline maths,
C-05's reduced-motion fix, C-11's vertical full-screen layout, C-12's
padding, C-18's item-as-tab-stop, the multi-aspect layout) is touched
only where it reads or writes the renamed hooks and dataset
properties; every inline custom property it writes
(--material-carousel-*) is untouched. The item renders the shared
md-focus-ring class (foundation/interaction.css) instead of a
hand-rolled ring, refined to an inset offset since an outward one
would draw under the neighbouring item. The previous/next buttons
mirror whole in RTL from carousel.css rather than through
<x-icon mirror-rtl>, which <x-button icon> has no prop to reach (a
component outside this batch); the technique matches how the
Tailwind-era markup already mirrored the whole button. The overlay
label's literal white ink over the scrim (C-25) is kept, with the
same reasoning as before.

Hooks renamed data-material-carousel(-item/-surface/-content/-label)
-> data-md-carousel(-item/-surface/-content/-label), data-padding(-end)
-> data-md-padding(-end), data-centered -> data-md-centered, updated in
the same commit: resources/js/carousel.js, tests/Feature/Components/
CarouselTest.php (rewritten on data-md-* and ComponentStylesheet) and
tests/Browser/CarouselTest.php. Browser tests owed by
docs/plans/material-3-browser-tests.md, added but not run: the
multi-aspect carousel's previous/next, arrow keys, Home and End
(scoped by data-md-carousel="multi-aspect" rather than a position in
the showcase, so reordering its examples cannot silently mis-target
the wrong carousel); a reduced-motion click on an item cut off only by
the row's own edge, which documents rather than fixes a real gap —
isMasked()'s inset check is always false once C-05 zeroes every
item's inset, so the click-to-reveal affordance does not fire there
(found by the Chromium baseline, step 32; fixing it is outside a hook
rename).

Imported from the Containment block of components.css.

/*
* <x-carousel-item>: one slide of an <x-carousel>, masked and shifted by the keyline maths
* carousel.css's header describes, unless the row is full-screen or multi-aspect, where nothing
* masks it at all (docs/reference/m3/components-actions-communication-containment.md § Carousel;
* docs/audits/m3-alignment/containment.md, C-11, C-12, C-25).
*
* [data-md-carousel-item] the tab stop (C-18), a focusable `group`, `md-focus-ring`
* [data-md-carousel-surface] the masked, shifted, extra-large-corner (28px) box
* [data-md-carousel-content] the slot (an <img>, cropped)
* [data-md-carousel-label] the "n of m"-named overlay on the scrim
* [data-md-carousel-label-text]
*
* The item renders the shared `md-focus-ring` class (foundation/interaction.css) rather than a
* hand-rolled ring — the box the class draws *is* the item's own whole hit area — refined here to
* an inset ring: an item sits edge to edge with its neighbours in the row, so the class's own 2px
* *outward* offset would draw under the next item instead of around this one.
*
* Full-screen: edge to edge, no corner, no mask — `--material-carousel-shift`/`-inset` go unread.
* Multi-aspect: the view writes the item's own `aspect-ratio` inline (`aspect`, a prop, held
* inside M3's 9:1616:9 range); the extra-large corner still applies but nothing masks it, since
* an Arrangement describes items of one size and a multi-aspect row has none. Selectors use `>`
* throughout, matching carousel.css, so a carousel nested inside an item never inherits its
* parent's layout rules.
*
* The label's ink is a literal `white`, not a role: it sits over `--md-sys-color-scrim`, which is
* black in every scheme, theme and contrast level, so white is the one ink that always has the
* scrim's contrast — a role (`inverse-on-surface`) is dark ink in a dark scheme and fails there
* (C-25, deliberately kept, as the component's original header explained).

* <x-carousel>: M3 Expressive's carousel — multi-browse, hero, uncontained, the uncontained
* multi-aspect-ratio layout (added November 2025) and full-screen, on a native scroll container
* with CSS scroll snap. resources/js/carousel.js ports Compose's keyline maths (Arrangement.kt,
* Keylines.kt, KeylineList.kt, Strategy.kt, KeylineSnapPosition.kt, Carousel.kt, androidx Compose
* Material 3 @ commit 7ac433e44e797de53af85226797862687f37735f, Apache-2.0) and writes the masks
* and sizes as inline custom properties every scroll frame; this file draws everything the script
* does not — the row's layout per layout, and the controls — and carousel-item.css draws the
* item and its mask (docs/reference/m3/components-actions-communication-containment.md
* § Carousel; docs/audits/m3-alignment/containment.md).
*
* [data-md-carousel] the row wrapper; its value is the layout
* [data-md-carousel-probe] hidden, measures the preferred item width for the script
* [data-md-carousel-scroller] the scroll container (role="region")

* [data-md-carousel-controls] previous/next, "auto" (pointer: fine only) or "always"
* [data-md-carousel-previous], [data-md-carousel-next]
*
* Specs table: 16dp leading/trailing padding, 8dp top/bottom and between items, for every layout
* but uncontained (leading only) and full-screen (0, edge to edge — C-12); a `>` combinator
* throughout, never a bare descendant one, because a carousel item can itself hold a nested
* carousel (a `multi-aspect` gallery inside a `hero` slide) whose own root would otherwise match
* its parent's rules too. Full-screen scrolls vertically, one edge-to-edge item at a time, capped
* at the 840px medium window it is meant for (C-11); reduced motion needs no rule here at all —
* the script writes zero inset, shift and full opacity itself for every layout (C-05).
*
* The previous/next icons mirror in RTL by scaling the whole button, as the row's arrow keys and
* scroll direction already do (`resources/js/carousel.js`'s own `state.rtl`), rather than through
* `<x-icon mirror-rtl>`: `<x-button icon>` has no prop to reach it, and flipping a round icon
* button whole reads the same as flipping only its glyph.
