Andreas Reinhold / reiniandClaude Opus 5 247c596c3a Cut duplicated and speculative code across the package
An over-engineering audit of the whole tree, applied in five reviewed
batches. Behaviour stays the same except where UPGRADE.md says otherwise.

PHP: the showcase and error-page stylesheets are prebuilt into
resources/dist by bin/stylesheets.mjs, through Vite's own postcss-import
(first occurrence kept, the order an application's build gives), instead
of Stylesheets::bundle() inlining imports on every request; only the
import walk DesignGuard needs stays. SchemeStylesheet::withProfiles()
replaces three copies of the scheme-plus-profiles loop, material:scheme
leaves spec and contrast checks to the node script that already made
them, and the error page's scheme cache, the hashed view namespace, the
translations path with no lang/ folder and DesignGuard's 1.x-name hints
are gone.

JS: the androidx shape port progress.js and both bin scripts each carried
lives once in resources/js/shapes.js (the generated SVGs are unchanged);
util.js holds ringIndex(), ms(), reopenGuard() and remember(), which
were written out several times; listeners are released through
AbortController; tooltip.js's hoverPopover() serves the rich tooltip too.

CSS: every rule for an element inside the navigation rail queries
`--md-navigation-rail-value` instead of repeating the seven collapsed
conditions under five media branches; badge, alert, progress, slider and
button read one non-inheriting colour-role table (components/color.css);
the dialog chrome, the submenu's popover chrome, the chip's state layer
and touch target, and the visually-hidden inputs use the shared rules
they copied; foundation/tokens.css is folded into foundation.css.

Views: Support\Field and Support\Link replace the error-key, bound-value
and link-attribute blocks copied into the fields and link components;
the timepicker period group, the menu filter and the showcase head are
partials; the datepicker's steppers and entry fields are loops; component
docblocks no longer restate SKILL.md.

Tests and tooling: one dataset-driven ComponentStylesheetsTest replaces
four per-group files, DesignGuardTest and the layout-component tests use
datasets, browser tests share one ready() helper, CSS parsing lives in
ComponentStylesheet alone. docs/audits and the finding IDs citing it are
removed, as are pestphp/pest-plugin-laravel, the unused composer scripts
and check:font; the lint job runs in the feature job, which now installs
node packages so the prebuilt-stylesheet staleness test runs in CI.

Feature suite 1177 passed, Chrome browser suite 299 passed.

/*
* `<x-bottom-sheet>`: M3's modal and standard bottom sheets (SheetBottomTokens.kt, androidx
* Compose Material 3, Apache-2.0; docs/reference/m3/
* components-actions-communication-containment.md § Bottom sheets → Specs).
*
* [data-md-bottom-sheet] the wrapper; data-md-open, data-md-standard
* [data-md-bottom-sheet-scrim] modal only
* [data-md-bottom-sheet-probe] hidden, measures a stop's px height for a drag to settle on
* [data-md-bottom-sheet-panel] surface-container-low, extra-large top corners, elevation 1;
* data-md-preset while `heights`/`snap` gives it stops
* [data-md-bottom-sheet-handle] the drag target and M3's 48dp hit area
* [data-md-bottom-sheet-grip] the 32×4px bar, the shared classes' touch target
* [data-md-bottom-sheet-announce] a live region, only while stops exist
* [data-md-bottom-sheet-body], [data-md-bottom-sheet-title], [data-md-bottom-sheet-actions]
*
* 640px max width, centred; 28px top corners only (`DockedContainerShape` = CornerExtraLargeTop);
* 50dvh default open height under a ceiling of the screen less M3's 72dp top margin. It
* rises on emphasized decelerate and only falls on emphasized accelerate — the asymmetric timing a
* more specific selector for the open state supplies, since a CSS transition always takes its
* duration and easing from the *after-change* style (the technique resources/css/components/
* drawer.css also uses). `data-md-preset` adds the height-between-stops transition on the spatial
* spring, independent of the open/close slide.
*
* The handle's own 22px top/bottom padding (`SheetDefaults.kt`'s `DragHandleVerticalPadding`) is a
* literal — 22 is not on the measurement scale — matching alert.css's 12px for the same reason.
* The grip button draws the shared `md-focus-ring` and `md-touch-target` classes rather than a
* hand-rolled ring: its own visible bar is not a smaller indicator drawn inside a bigger box those
* classes cannot reach (unlike the datepicker's day) — the box they draw *is* the button's whole
* hit area. The one refinement is the ring's offset, 4px rather than 2px, as the old handle drew
* it: 2px from a 4px-tall bar leaves the ring hard to tell from the bar.
*
* The scrim fades out as it fades in, and the state rules match the root's own scrim and panel,
* so a sheet nested in an open one (a menu's sheet at compact inside a sheet) keeps its own state.
* Both keep `x-show`, and the view's `x-transition` holds their `display` through the exit rather
* than `allow-discrete`, which Firefox does not honour for `display` (see drawer.css); Alpine holds
* for the first `transition-duration` listed, so the closing slide is listed first.
