`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).

Components read the device's safe-area insets straight from env(), which a
browser test cannot fake and an application drawing its own status strip
cannot extend. Every inset the package reads, in its CSS and its views, is
now var(--material-safe-top|bottom|left|right, env(safe-area-inset-…)):
unchanged while the variables are unset.
The app shell's --material-bottom-bar also adds
var(--material-bottom-extra, 0px), so an application that docks something on
the phone's navigation bar (an offline banner) sets its height once and the
snackbar, a fab button and the page's bottom padding clear it.
A guard test fails on any env(safe-area-inset-*) outside such a variable, and
AppShellTest's assertion on the bar height's class follows the new value.

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.
