Andreas Reinhold / reiniandClaude Opus 5 ab692b66bb Add the navigation bar, navigation rail and app shell
M3 Expressive's flexible navigation bar, the collapsed, expanded and
modal navigation rail with its state applied before the first paint,
and an adaptive app shell composing them. The head script now restores
the theme and rail attributes that wire:navigate strips from <html>.
Completes Phase 8.

{{-- The theme and the navigation rail's width, decided before the first paint. Include it in
<head>, ahead of @vite.
It reads the visitor's choice from localStorage (`livewire-material.theme.storage_key`):
`light`, `dark` or `system`, falling back to `theme.default`. `system` follows the
operating system, now and whenever it changes. The result is written to
<html data-theme>, which is the only thing the stylesheet keys on; the choice itself is
<html data-theme-choice>, where `$store.theme` picks it up.
A value under one of `theme.legacy_keys` an earlier toggle's key, which may be
JSON-encoded (maryUI's `"dark"`) is adopted once and removed. Nothing is written for a
visitor who never chose, so changing `theme.default` later reaches them too.
The rail rides along for the theme's reason: <html data-rail> is `expanded` or `collapsed`
(`livewire-material.rail.storage_key`, falling back to `rail.default`), and a collapsible
rail's width is CSS keyed on it (the `rail-collapsed:` variant). Set any later, a collapsed
rail would paint wide and snap shut on every load. `$store.rail` (resources/js/navigation.js)
changes it.
wire:navigate swaps the body, merges the head without running this again, and gives <html>
the next page's attributes — which the server rendered without any of these, so Livewire
removes them. They are put back as the new page is swapped in (`onSwap`, in the same task,
before anything paints), so this only has to run on a full load. --}}
