M3's optical size axis redraws a symbol so its strokes look equally heavy at
every size; drawing the 24 cut at 20px thins them by about a sixth (styles.md
§ Icons). `optical` picks the cut — 24 by default, 20 for an icon drawn at 20px
or smaller — and combines with `filled`; anything else falls back to 24, so no
caller can land on a folder that does not exist. SvgFile::symbol() takes the
size as a fourth argument and resolves the `-20` folders; the catalogue is the
same in both cuts, so symbolNames() and DesignGuard's icon-name check are
unchanged. The callers that size their own icons pass it in a later step.
Plan step 10; finding C16.

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.
