Andreas Reinhold / reiniandClaude Opus 5 a99fbd3794 Build the theme and contrast rows on the connected button group
`mode="picker"` hand-rolled an outlined segmented button, point for point the
design M3 Expressive deprecates, and its own arrow keys neither wrapped nor
handled Up/Down. Both rows are now <x-group>: native radios in a fieldset, so the
browser supplies the radiogroup, both axes, the wrap and the roving tab stop, and
the store is bound through an x-model accessor — a contrast row still marks the
resolved level but writes through setContrast(). A new `label` prop legends the
row. Plan: docs/plans/material-3-alignment.md, step 14 (navigation N-04, N-17).

{{-- Switches the colour theme through `$store.theme` (resources/js/theme.js), so every toggle on a
page reads and writes the one choice and none needs an id.
`mode`:
- `toggle` (the default): an icon button between light and dark. The icon is where it takes
you a sun while the page is dark, a moon while it is light and it is a toggle button,
"Dark theme", pressed while dark.
- `cycle`: an icon button that steps light dark system, showing the choice it is on.
- `picker`: the three choices as a connected button group, for a settings page.
- `contrast`: the same row for M3's three contrast levels — standard, medium (3:1) and high
(7:1), the three the scheme is generated in. The row marks the level in force
(`resolvedContrast`), so the operating system's setting shows while the choice is
`system`, and choosing one is an explicit choice from then on.
The two rows are `<x-group>` M3 Expressive's connected button group, the successor of the
segmented button, which the expressive update deprecates. Its segments are native radios, so
the browser supplies the radiogroup semantics, both arrow axes, the wrap and the roving tab
stop; the store is bound through an `x-model` accessor on the wrapper, since the level a
contrast row marks is the resolved one but the level it writes goes through `setContrast()`.
`label` adds a visible legend (a settings page); without one the row is still named for a
screen reader. `class` lands on the button or on the group.
The theme is the visitor's, known only in the browser, so the parts that depend on it wait for
Alpine (`x-cloak`, an unchecked radio) rather than render a guess. --}}
