Subject: [PATCH] Take the typescale's tracking from Compose, and reset
 roundness

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).

Plan: docs/plans/material-3-alignment.md step 4, findings core C5, C6, C7.

+ *   ROND  0–100   — the roundness axis every `type-emphasized-*` utility sets to 100. Re-subset
+ *                   the font without it and the emphasized styles quietly stop being round.

+- Type: `type-{display|headline|title|body|label}-{lg|md|sm}` and `type-emphasized-…` — M3's 15 styles and their emphasized twins, one weight step heavier, rounder, with their own tracking. Never assemble `text-*`, `leading-*` and `tracking-*` by hand; a utility carries size, line height and tracking together. Emphasis is deliberate and one element at a time (M3 asks for it on badges, primary buttons, selected rows, headlines), so a regular utility inside an emphasized one goes back to plain. The font is Google Sans Flex (`font-sans`).
 - Shape: `rounded-corner-{none|xs|sm|md|lg|lg-increased|xl|xl-increased|xxl|full}`.
 - 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). Always pair an easing with its duration: `duration-(--md-sys-motion-spatial-fast-duration) ease-spatial-fast`. Reduced motion zeroes the durations.
