 - `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.

 - `mode`: `collapsed`, `expanded`, `collapsible` (default: expanded until its menu button collapses it; the choice is `$store.rail`, remembered and applied before the first paint), `modal` (collapsed in the layout; the menu button or `$store.rail.show()` opens it expanded over a scrim, focus held until Escape, the scrim or leaving the page), `adaptive` (`<x-app-shell>`'s, one rail per window size class: hidden and opened as a modal on a compact window, collapsed and opened as a modal at `medium`, a standard rail from `expanded` — collapsed there, expanded from `large`).
-- Props: `label` ("Main"), `width` (expanded width, `16rem`, held between 220 and 360px), `menu` (the menu button; on by default for `collapsible`, `modal`, `adaptive`). Slots: `brand` (beside the menu button, expanded only), `header` (a FAB), the destinations (the only part that scrolls), `footer`. In a flex row the rail sticks to the top of the viewport.
-- Anything inside a rail takes both shapes with the `rail-collapsed:` variant, true while that rail is drawn collapsed for whatever reason: `<span class="rail-collapsed:hidden">…expanded only…</span>`, `<span class="hidden rail-collapsed:inline-flex">…collapsed only…</span>`. Put the variant on a wrapper, never on a component. Nothing that shows while collapsed may be wider than 96px.
+- Props: `label` ("Main"), `width` (expanded width, `16rem`, held between 220 and 360px), `menu` (the menu button; on by default for `collapsible`, `modal`, `adaptive`), `divider` (M3's optional vertical divider on the page's side — use it when the page scrolls under a fixed rail), `fill` (`false` for a transparent container, which M3 allows while the items keep 3:1 contrast). Slots: `brand` (beside the menu button, expanded only), `header` (one `<x-fab label icon>`, which the rail morphs into an extended FAB and back as it expands — it also rests at elevation 0, as M3 asks of a nested FAB), the destinations (the only part that scrolls), `footer`. In a flex row the rail sticks to the top of the viewport.
+- Anything else inside a rail takes both shapes with the `rail-collapsed:` variant, true while that rail is drawn collapsed for whatever reason: `<span class="rail-collapsed:hidden">…expanded only…</span>`, `<span class="hidden rail-collapsed:inline-flex">…collapsed only…</span>`. Put the variant on a wrapper, never on a component. Nothing that shows while collapsed may be wider than 96px.
+- A `collapsible` rail is held to the collapsed 96px below `medium` (600px), where M3 says to use a navigation bar rather than a standard rail. `collapsed` and `expanded` are fixed-width by design: wrap one in a `medium:` element if it must not show on a phone.
 - `<x-navigation-rail-item>`: the same props as `<x-navigation-bar-item>`. `<x-navigation-rail-section label="…">`: a group with a heading that shows only while the rail is expanded; it names the group for screen readers either way.
 - `$store.rail`: `collapsed`, `toggle()`, `collapse()`, `expand()` (the remembered choice; `auto` is true while nothing is stored, so an adaptive rail takes its window size class's default instead, and the first choice clears it), `open`, `show()`, `hide()` (the modal rail; closed on every `wire:navigate`). `config/livewire-material.php` → `rail.default` (`expanded` or `collapsed`) and `rail.storage_key` (`material-rail`).

Every toggle on a page shares the store. Both rows are `<x-group>` — a connected button group over native radios, so the arrow keys, the wrap and the roving tab stop are the browser's; `label` adds a visible legend, and without one the row is still named for a screen reader. Nothing is checked until Alpine has read the store, because the theme is known only in the browser.
