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-collapse>: not an M3 component — M3 has expandable list items and menu expansion but no
* standalone disclosure — built on the native `<details>` so it opens without script, keeps its
* state through a Livewire morph, and is announced as a disclosure by the browser. Judged against
* foundations rather than any M3 component spec, since M3 has no standalone disclosure.
*
* The height eases open and shut on the fast spatial spring, the same one that turns the chevron,
* from resources/js/collapse.js: it animates the `<details>`' own `block-size`. This file cannot —
* `interpolate-size` (for `0 -> auto`) is Chrome's alone, and Firefox does not hold the content's
* `content-visibility` through a close — so Firefox and Safari used to snap open and shut. While a
* close runs, `open` is still set and `data-md-collapse-closing` turns the chevron back at its
* start. Under reduced motion the duration token is zero (tokens/motion.css), and the section
* snaps, as the browser draws it.
*
* `data-md-variant="filled"` is a surface-container tile with a large corner; the summary inherits
* it (`border-radius: inherit`) so the shared `md-state-layer`'s own `::before`, which also
* inherits, draws inside the same shape. `md-state-layer` and `md-focus-ring`
* (foundation/interaction.css) sit on the summary; this file only refines their target — the
* 48px summary height, the icon and chevron colour — never their opacities or ring.
*
* Icon-to-title and title-to-chevron gaps are a literal 12px: the measurement scale has no 12
* (`space125` is 10px), as alert.css's gap. Every part is matched as its own `<details>`' child, so
* a collapse nested in a filled one takes neither its padding nor its turned chevron.
