Plan step 23, containment.md § Missing ("Carousel: the uncontained
multi-aspect-ratio layout"). `<x-carousel layout="multi-aspect">` is the
layout M3 added in November 2025: each `<x-carousel-item aspect="…">`
keeps its own ratio at the row's fixed height, held inside M3's 9:16 to
16:9 range (a square by default), with 16dp leading padding, 8dp gaps,
the extra-large corner and uncontained (default) scrolling.
The keyline machinery does not fit it: an Arrangement counts items of
one size each, and every snap position and mask follows from that size.
So the layout is a plain flex row, unmasked, and carousel.js only
measures each item's resting position off the DOM, which keeps the
previous/next buttons, the arrow keys, Home/End and bring-into-view
working. The header and SKILL.md say so.

Plan step 23, containment.md § Missing ("Bottom sheets: preset heights
and the handle's cycle-through-heights behaviour"). `heights` (or `snap`,
which is 25/50/90dvh) lists the stops a sheet moves between; it then
takes its stop's height and opens at the stop that equals `height`, or at
the first. Fewer than two stops is no stops, since M3 only requires the
non-drag alternative "if multiple preset heights exist".
That alternative is the drag handle, which M3 names a button: activating
it moves to the next stop and announces it in a live region, and from the
last stop it closes the sheet — M3's "selecting the drag handle toggles
preset heights or closes the sheet", and the same thing a handle with no
stops has always done. A drag now runs the sheet's height with the
pointer and settles on the nearest stop, or closes below the smallest one
or on a downward flick.

Plan step 23, containment.md § Missing ("Side sheets: a genuine standard
variant"). `<x-drawer standard>` is M3's other side-sheet variant: from
`expanded` it is co-planar with the content — no scrim, no focus trap,
nothing inert, 0dp elevation, `surface` rather than surface-container-low,
no corner, and an outline-variant rule down its inner edge in place of the
scrim — sitting in the page flow at the window's full height. Below
`expanded` it is the modal sheet, since M3 caps a side sheet at 400dp and
a medium window has too little left beside one. Capped at that 400dp
whatever `width` says, and it always draws the close affordance M3
requires, because nothing else closes it there.
`pane` is untouched and the header and SKILL.md say how the two differ:
pane is the list-detail companion, standard is supplementary content.

Plan step 23, containment.md § Missing ("Cards: the dragged state").
`data-dragged` on `<x-card>` takes the top of M3's card elevation scale
— Level4 (8dp) elevated, Level3 (6dp) filled and outlined — under the
16% dragged state layer from tokens/state.css. The row's hover and press
rules now exclude a dragged card, so the card a pointer is holding stays
at its dragged level. The application owns the attribute: nothing in the
browser tells a card it is being carried.

Plan step 23, containment.md § Missing ("Lists: leading video slot").
`<x-list-item video="…">` (or `<x-slot:video>`) draws M3's leading media
in its landscape sizes: 100×56px in a two-line item, 114×64px in a
three-line one (ListTokens' LeadingVideoSmall 56×100dp and
LeadingVideoLarge 64×114dp), with the small corner the leading image
takes. The tallest element sets an item's height, so a video lifts the
item to at least the 72px two-line row — 56 + 2×8 is 72 exactly, and
64 + 2×12 is 88.

Plan step 19, containment.md C-11. The full-screen layout was another
horizontal row with a 28px corner and a mask, where M3's "shows one
edge-to-edge large item at a time and scrolls vertically". It is now a
vertical scroll-snap column: items fill the row with no corner and no
mask, 16dp apart, no end padding, the previous/next buttons point up and
down and the arrow keys are Up and Down. The row is capped at the 840px
medium window, which with the portrait rule in the header comment is as
far as CSS can hold M3's "compact and medium, portrait only". The ported
FullScreenCarouselStrategy keylines go with it: nothing measures them
any more.

M3 asks the rail to animate its FAB into an extended FAB as it expands; the
documented pattern was two FABs swapped by `display`, so the collapsed one
appeared at once while the rail's width was still springing. The header now takes
one <x-fab label icon> whose label springs open and shut on the rail's own
spring — and names it at both widths, where the collapsed FAB had needed a
tooltip to have a name at all.
M3 also lists two container treatments as optional that the library had neither
of: `divider` draws the vertical divider on the page's edge, which is its own
answer to a page scrolling under a fixed rail, and `fill="false"` drops the
container colour. Neither reaches a rail open over a scrim. And a `collapsible`
rail, whose width is the visitor's choice rather than the window's, is held to
the collapsed 96px below `medium`, where M3 asks for a navigation bar instead.

Plan step 19, containment.md C-18. The row was the focusable `region`
and the items were not focusable at all, which is the thing M3's
accessibility page draws a Don't for: "use Tab to place initial focus on
the first carousel item", "avoid focusing on the carousel container".
Each item is now `tabindex="0"` with the focus ring drawn inside it, the
row is out of the tab order, and from a focused item the arrows move one
item (moving focus with them), Home and End go to the ends, and Space or
Enter opens one that is not fully in view.

A plain tooltip vanished the instant the pointer left, where M3 keeps one for
1.5s and shows only one at a time — these are popover="manual", so nothing was
closing the last one. A rich tooltip's bubble was never associated with its
trigger at all, so the explanation it exists to give was never announced; the
script now writes aria-describedby (and aria-haspopup/aria-expanded when it is
persistent) onto the focusable control in the trigger slot, and again after a
morph. Plan step 18, actions.md ACT-22, ACT-25.

Shift+M and Shift+Y reach the month and year dropdowns, which is M3's
date picker keyboard table; Home and End go to the ends of an open
combobox list, and stay the field's own caret keys when it is closed. The
password reveal drops aria-pressed and keeps only its flipping label, so
a screen reader hears the state once rather than twice and inverted. The
radio's `inline` now says that M3 cautions against a row and wants an
option chosen on load.

Plan step 19, containment.md C-12 and C-25. `padding` defaulted to 0
where M3's specs table gives every layout 16dp of leading and trailing
padding — leading only for `uncontained`, none for the edge-to-edge
`full-screen` — so the default is 16 and each layout now says which
ends it applies to (`data-padding`, `data-padding-end`). The row gains
the 8dp above and below that goes with it, without shortening the
items. The overlay label is `inverse-on-surface` instead of a literal
`white`, which no scheme or contrast profile follows.

A floating dot sat 2px inside the icon's top-trailing corner where M3 puts it
flush, and a floating count 4px above it where M3 says 2px. An `outline` status
label drew its edge in outline-variant, the decorative role dividers use, which
is about 1.5:1 on surface — M3 asks a badge for 3:1, so it takes `outline`.

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.

An error or warning alert was role="alert", an assertive live region — but the
usual alert is part of the page as it renders, which some screen readers then
announce over the page title, and a Livewire morph re-announces. It is now
role="status" whatever its colour, with an `assertive` prop for a notice put on
screen in answer to something the person just did. Its 40px dismiss button takes
the shared touch-target. Plan step 18, actions.md ACT-18, ACT-36.

M3 wants two visual indicators per state and names the pair for a text
field: the error colours and a trailing error icon. The field now draws
one, labelled "Error", unless the caller already trails it or the field
is xs. A read-only field loses its dashed outline: M3 keeps "the same
visual style as an editable field", and the native readonly attribute is
what tells a screen reader. The data-readonly hook stays.

M3 says to avoid an icon in a snackbar and gives the supporting text no fourth
colour, so the state glyph and the 80% description are gone: a type now only
picks the announcement role. The 40px action and close buttons take the shared
touch-target, Escape dismisses a snackbar that holds the focus, and the host
publishes --material-snackbar-height on <html> so a `fab` button sits above the
snackbar instead of under it. Plan step 18, actions.md ACT-17, ACT-18, ACT-20,

Density was applied to every fine-pointer device with no way out, which
M3 forbids outright: "don't apply density by default; offer an explicit
density opt-in instead, keeping opt-out targets at >= 48x48 CSS px". A
row is now 52px and `dense` is a prop that tightens it to 36. The row
divider also takes outline-variant itself rather than 60% of it, since M3
keeps opacity for state layers and disabled.

"Toggle menu" and is always written. The list had no ceiling, so six items ran

1 to 2, filled and outlined 0 to 1) with the layer over it. The 12 to 16
corner morph on hover is gone: M3 gives a card one shape and lists shape
morph for buttons, FABs and list items only. New `actionable` prop for

Five or more sections wrapped onto a 3- or 4-column grid, which left the tab
bar's divider under the last row only and stranded every upper row's active
indicator against nothing. From five they are now what M3 prescribes and its

offset 52dp. Four or fewer still share the row. The 20px icons take the 20 cut.

M3 is explicit twice over — never disable a FAB, remove it instead — and the
prop painted the full disabled treatment with nothing warning against it. It is
gone; hiding the FAB is the documented answer. The extended FAB's icon-to-label
gap goes to M3's 16dp at md and 20dp at lg, the small one takes the baseline's
80dp minimum width, and the root gains a `data-fab` hook for a place that draws

Items were 44px tall with the baseline menu's 12px sides, the separator had half

48px rows with 16px either side, an 8px separator, disabled items focusable but

M3 asks a FAB's icon and a default (non-toggle) icon button's icon to be filled,

`$selected === null` case changed. Every glyph these components draw at 20px now
passes `optical="20"` for the cut M3 draws at that size — button xs/sm, group,

list keeps `role="list"` and marks a selected item `aria-current`. A
selected option draws a trailing check as M3's second cue, which
`icon-right` replaces. The item reads its list's mode with `@aware`.

the wrapper idiom (`max-medium:hidden`), `<x-app-shell>`'s section gets a table

`<x-modal fullscreen>`, `<x-button fab|responsive>`, `<x-navigation-bar>`,

`expanded:` 840, `large:` 1200, `extra-large:` 1600, Tailwind's screens cleared,
scripts through resources/js/breakpoints.js, a container query (`@md:`) a

bin/springs.mjs is the sampler behind motion.css: damping ratio and stiffness in,
the 49-point linear() and the settle time out. Run with --settle it reproduces
the six curves the file carried byte for byte, so only the window changed.
Each spring is now sampled over the duration M3 publishes for the web (spatial
350/500/650 ms, effects 150/200/300 ms) instead of stopping at its own settle
time, so the *-duration tokens read Google's numbers. Sampling stays in real
time — point i is the spring at duration × i / 48 — so the bounce lands at the
same millisecond as before; a longer duration just holds the tail flat at 1, and
a shorter one pins the last point, at most 0.3% of the travel in one frame. Each
token's comment records damping, stiffness, settle time and sampled duration.
M3's second motion scheme is here too: [data-motion="standard"] swaps the three
spatial springs (damping 0.9, 0.2% overshoot instead of 9%) and their durations;
the effects springs sample identically in both schemes, so they are shared. The
reduced-motion block names both selectors, so it still zeroes every duration.

Tracking now comes from androidx's TypeScaleTokens.kt as sp/16 rem, so Display
Large is -0.0125rem, Title Medium and Body Medium 0.0125rem where material-web's
pre-Expressive numbers stood. The emphasized set gets its own
--md-sys-typescale-emphasized-<style>-tracking, which the emphasized utilities
read: M3 widens four of them and takes Display Large back to zero. Every regular
utility sets `font-variation-settings: normal`, because the property inherits and
body copy inside an emphasized heading is meant to read as itself.
bin/check-font.mjs (fontkit) prints the packaged woff2's fvar axes, so a
re-subset cannot silently drop the ROND axis the emphasized styles depend on;
`npm run check:font` runs it and tests/Feature/FontTest.php runs it through the
configured node binary, skipping when node cannot run (PHP cannot open a woff2
without Brotli).

M3's optical size axis redraws a symbol so its strokes look equally heavy at
every size; drawing the 24 cut at 20px thins them by about a sixth (styles.md
§ Icons). `optical` picks the cut — 24 by default, 20 for an icon drawn at 20px
or smaller — and combines with `filled`; anything else falls back to 24, so no
caller can land on a folder that does not exist. SvgFile::symbol() takes the
size as a fourth argument and resolves the `-20` folders; the catalogue is the
same in both cuts, so symbolNames() and DesignGuard's icon-name check are
unchanged. The callers that size their own icons pass it in a later step.
Plan step 10; finding C16.

<x-app-shell> passed no badge label to its rail and bar items, so a badge
like 0/3 reached a screen reader bare; a destination's badgeLabel now does.
The head script indexed the profiles with a null scheme when none are
configured, which PHP 8.5 reports as a deprecated null array offset on every
page with theme.meta on. It reads the default scheme without the lookup.
