Plan step 35: <x-pane>, a content region with M3's margins (16px below
medium, 24px from it) drawn once however panes and layouts nest, a width
cap, and an optional pane app bar - <x-app-bar> as a direct child of the
pane with title, subtitle, actions, a back link or action, a leading
slot, and the section navigation under it.

Plan step 35: <x-surface level padding corner outlined>, a tonal region
in surface or a surface-container step, padded with a spacing token,
rounded with a corner token and optionally edged in outline-variant. A
pane on a surface keeps its margin again, since the surface is a new edge.

Plan step 35: <x-grid :columns gap min-item>. The column count per
breakpoint is written as five inline custom properties, each filled from
the nearest smaller breakpoint, so a nested grid never inherits its
parent's; min-item fills a row by the room the grid has, and with columns
the counts become a ceiling.

Plan step 35: <x-row gap align justify wrap stack-below>, children side
by side in a pane and stacked under one another below an M3 breakpoint,
in the inline direction so a right-to-left document mirrors it.

Plan step 35: <x-stack gap align>, the first of M3's layout components,
with what they all share - src/Support/Layout.php reading the props into
data-md-* attributes, the spacing-token gap and padding rules, the
hide-below/hide-from rules in material.visibility, the stylesheet checks
for resources/css/layout, the browser test file and the skill's Layout
group. The Workbench puts the material layers above Tailwind's preflight,
which would otherwise zero every layout padding and margin.
