Offer the app shell a window-wide banner above the rail
M3's scaffold is bars, then rails, then panes, and the shell had no slot that rendered above the rail: an application-wide bar could only be a pane bar beside it. `banner` is that slot — the shell is a column now, with the rail and the page as one row inside it — and the rail sticks under a pinned banner through --material-banner rather than behind it. `top` still means the page's own bar. Plan: docs/plans/material-3-alignment.md, step 21 (navigation N-14).

- `destinations`: `title`, `icon`, `url`; optional `active` (default: the URL is the page's, also during a Livewire update request), `badge` (`true` for a dot, or a count), `badgeLabel` (what a screen reader hears for the badge: "3 unread"), `section` (a heading in the rail, shown only while it is expanded; consecutive destinations with the same section are grouped), `bar` (default `true`; `false` keeps it out of the bottom bar — M3 wants three to five there), `navigate` (`false` for a full page load instead of `wire:navigate`).
|
||||
- Slots, each rendered once: `brand` (beside the rail's menu button, expanded only), `rail-header` (a FAB), `rail-footer` (pinned to the foot of the rail), `actions` (a row of icon buttons at the very foot, stacked when collapsed), `top` (the app bar, above the page at every width), and the page. `label` names the landmarks ("Main"); `rail-width` is the expanded width (`16rem`).
|

- Slots, each rendered once: `banner` (a bar across the whole window, above the rail and the page), `brand` (beside the rail's menu button, expanded only), `rail-header` (a FAB), `rail-footer` (pinned to the foot of the rail), `actions` (a row of icon buttons at the very foot, stacked when collapsed), `top` (the page's own bar, above the page and beside the rail), and the page. `label` names the landmarks ("Main"); `rail-width` is the expanded width (`16rem`).
|

- `banner` or `top`: M3's scaffold is bars, then rails, then panes. An application-wide bar — one search, one account menu, the same on every page — goes in `banner` and the rail starts under it; a bar that titles the page goes in `top`, beside the rail. Never both. A banner that pins itself to the top of the window says how tall it is (`style="--material-banner: 4rem"` on `<x-app-shell>`), so the rail sticks under it instead of behind it.
|
||||
- The rail is one element at every width: what is in it is also what a phone sees in the modal rail. On a compact window nothing opens it but `$store.rail.show()`, so a page whose destinations are not all in the bar needs a menu button in its app bar (hidden from `medium`).
|
||||
- `--material-margin` is M3's window margin (16px compact, 24px from `medium`) and the content region already carries it, so a page inside the shell writes no gutters of its own; something that must reach the window's edges opts out with `-mx-(--material-margin)`.
|
||||
- Two panes side by side are M3's from `expanded`: `<x-drawer pane>` is the second one, in an `expanded:flex expanded:items-start expanded:gap-6` row inside the page.
