SealShare's only navigation is a floating toolbar at place="bottom". In
1.x it set --material-bottom-bar to lift the snackbar over it; in 2.0.0
the toolbar reads that variable to place itself, so an application can
no longer set it, and the snackbar landed on the toolbar. M3 nudges a
snackbar "upward to avoid overlapping FABs/docked toolbars" and never
puts one in front of navigation.
A bottom-placed toolbar now publishes --material-bottom-toolbar, the
distance from the window's bottom edge to its top: floating 64px (as
tall as an md or lg FAB beside it), docked 64px plus the safe area it
pads, rounded docked floating from 840px. It is declared on :root and
again on the scaffold's root, the only place its formula sees the bar.
The snackbar clears whichever of the bar and the toolbar reaches higher,
and a page pads its end with it. Two Chromium tests, both failing on the
old formula: a docked toolbar on a scaffold's navigation bar, and a
floating toolbar without a scaffold (plan step 46).

Plan step 36 (navigation group, second stream): <x-toolbar>'s class
lists move into resources/css/components/toolbar.css, keyed on
data-md-toolbar (data-md-variant/-vertical/-vibrant/-rounded/
-toolbar-place) and data-md-toolbar-group/-toolbar-fab. The docked
form with a FAB (N-02's --material-bottom-bar clearance), the vertical
24dp margin (N-12), the standard toolbar's primary icon buttons
(N-13), and the rounded large-screen form with dividers from 840px
were all already correct; only their hooks, units and layer needed to
change. The file no longer sits outside every layer: button.css and
fab.css now draw their own ink through data-md-* attributes rather
than a Tailwind utility, so a toolbar's more specific selector always
beats their single base color/background-color/box-shadow declaration
without needing to escape the cascade layers.
Sizes stay px (64px row, 40px divider); spacing goes through the
measurement tokens where one matches the value (4px leading/trailing
gap, 16/32px docked spread, 8px floating ends, 16/24px placed
margins).
Hooks renamed: every unprefixed data-toolbar* attribute to data-md-*,
updated in tests/Feature/Components/{AppBarTest,ToolbarTest}.php and
tests/Browser/BarsTest.php. toolbar.js needed no change: it reads the
bar through $root and role="toolbar", not by hook name.
Carry-over from the app-bar step: layout/pane.css now imports
app-bar.css and button.css for the pane's own top app bar and back
button, now that both are rewritten. That import crosses into
material.components for the first time from a layout file, so
tests/Feature/StylesheetsTest.php's two layout-shape checks now skip
non-`layout/` files reached through it — each already covered by its
own group's stylesheet test.
Added the owed browser tests (docs/plans/material-3-browser-tests.md):
a docked toolbar clear of the navigation bar below medium, and the
rounded form with its divider height from 840px, clear of the
window's edges.

Plan step 35: <x-app-shell> becomes <x-scaffold>, M3's and Compose's name
for the structure of bars, rails and panes, with no alias; every package
view, the showcase, the tests, the skills, README and UPGRADE follow. Its
markup and Tailwind classes stay for the navigation rewrite. The new fab
slot places the FAB as Compose's Scaffold does - bottom-end, 16px from the
edges below medium and 24px from it, clear of the navigation bar and of a
snackbar on screen (resources/css/layout/scaffold.css) - and the content
region tells a pane inside that the margin is already drawn.

Plan step 25, item 8 (navigation Missing: "Toolbar, large-screen
treatments"). M3's toolbar guidelines (Adaptive design, Resizing) say it
of the docked toolbar: "On web and large screens, the docked toolbar can
be rounded. Dividers can be used to organize large amounts of items",
and it can be placed in different parts of the page. `rounded` does that
from expanded (840px): fully rounded, spanning its container, lifted
16px off the window's edges at place="bottom"; below expanded it stays
the square full-width bar. An <x-divider vertical /> between groups of
controls stands as tall as the icon buttons inside any toolbar. The
floating toolbar is already fully rounded and gets no new form.

Plan step 25 (navigation Missing): M3's toolbar configuration table lists
"With FAB" for both toolbars, but the `fab` slot was gated to the floating one.
A docked toolbar now takes it at its end, inside the toolbar where the arrow
keys reach it; its controls gather at the start, and the FAB rests flat on the
bar — elevation 0 for a FAB nested in another component, as Compose's
bottomAppBarFabElevation is.

`place="bottom"` ignored --material-bottom-bar, so a floating toolbar overlapped
the shell's navigation bar and a docked one landed squarely on it. Both now clear
it — max(), not a sum, since that height already swallows the bottom safe area —
and the docs say what M3 says: never show a docked toolbar and a navigation bar
together. Plan: docs/plans/material-3-alignment.md, step 14 (navigation N-02).

M3 Expressive top app bars (small, centered, medium and large flexible,
search) that collapse with CSS sticky, docked and floating toolbars,
primary and secondary tabs with a view-transition indicator, section
navigation, the account menu and theme toggles.
