bin/springs.mjs is the sampler behind motion.css: damping ratio and stiffness in,
the 49-point linear() and the settle time out. Run with --settle it reproduces
the six curves the file carried byte for byte, so only the window changed.
Each spring is now sampled over the duration M3 publishes for the web (spatial
350/500/650 ms, effects 150/200/300 ms) instead of stopping at its own settle
time, so the *-duration tokens read Google's numbers. Sampling stays in real
time — point i is the spring at duration × i / 48 — so the bounce lands at the
same millisecond as before; a longer duration just holds the tail flat at 1, and
a shorter one pins the last point, at most 0.3% of the travel in one frame. Each
token's comment records damping, stiffness, settle time and sampled duration.
M3's second motion scheme is here too: [data-motion="standard"] swaps the three
spatial springs (damping 0.9, 0.2% overshoot instead of 9%) and their durations;
the effects springs sample identically in both schemes, so they are shared. The
reduced-motion block names both selectors, so it still zeroes every duration.

Tracking now comes from androidx's TypeScaleTokens.kt as sp/16 rem, so Display
Large is -0.0125rem, Title Medium and Body Medium 0.0125rem where material-web's
pre-Expressive numbers stood. The emphasized set gets its own
--md-sys-typescale-emphasized-<style>-tracking, which the emphasized utilities
read: M3 widens four of them and takes Display Large back to zero. Every regular
utility sets `font-variation-settings: normal`, because the property inherits and
body copy inside an emphasized heading is meant to read as itself.
bin/check-font.mjs (fontkit) prints the packaged woff2's fvar axes, so a
re-subset cannot silently drop the ROND axis the emphasized styles depend on;
`npm run check:font` runs it and tests/Feature/FontTest.php runs it through the
configured node binary, skipping when node cannot run (PHP cannot open a woff2
without Brotli).

The scheme script always generated with material-color-utilities' 2025 spec.
An application whose palette was generated with M3's original 2021 colour
(ReStride) could not reproduce it. The script now takes `spec` ('2025' by
default, or '2021') and refuses anything else, and the command takes
`--spec`, validated before Node runs.
Colour profiles may set their own `spec`, `success`, `warning` and `info`;
without them the command's options apply. The stylesheet header writes out
every option that differs from its default, so the recorded command
regenerates the file, and a profile whose spec differs from the header's
names it. Default output is byte-for-byte unchanged.

<x-button> (label buttons, icon buttons and toggles in five sizes, with
filled, tonal, outlined, elevated and text variants in any colour role),
<x-tooltip>, <x-menu> with items, groups and separators, <x-button-group>,
<x-group> as a connected button group, <x-split-button>, <x-fab>,
<x-fab-menu> and <x-loading>. Sizes, colours and shapes come from
androidx Compose Material 3's tokens; the loading indicator ports its
Morph into SVG + SMIL.
Menus follow WAI-ARIA's menu button pattern on popovers placed by CSS
anchor positioning. Browser tests run in Chromium, Firefox and WebKit.
The showcase fetches the icon names on demand: inlined, they tripped
Pest's test server into HTTP 431s under Firefox.

Colour, shape, type, elevation and motion as tokens and Tailwind
utilities; `php artisan material:scheme`, which generates an app's colour
roles with Google's material-color-utilities (spec 2025); the theme head
script with light, dark and system and its Alpine store; Google Sans Flex;
every Material Symbol (4,135, outlined and filled) drawn by <x-icon>
without blade-icons; all 35 M3 Expressive shapes, ported from androidx, as
<x-shape>; the x-figure directive; the Toasts concern; DesignGuard for
applications' tests; and a showcase with every token, both themes side by
side and an icon search.
Colour utilities are `@theme inline`, so a section with its own
data-theme repaints; without it they resolve once on :root.
