An output only reaches a parent @binding when the component calls
output.<name>(). Two separate faults meant most of the library never got
there, and both failed silently at each end.
HTML lowercases attribute names, so a parent's @sizeChange registered under
"sizechange" while the component emitted "sizeChange". The lookup missed, fell
through to a DOM dispatch, and the binding was never invoked. That made all 17
camelCase outputs undeliverable -- DataTable.pageChange and .rowClick,
Map.markerClick, ChatBubble.messageClick, LayoutSplitter.sizeChange and the
rest. invokeComponentOutput now falls back to a case-insensitive lookup, and a
csr test fails without it.
Separately, 18 components dispatched hand-built CustomEvents rather than
calling output.*. A bubbling event on the component's own root never reaches a
binding, because parent handlers live in a registry only the output proxy
reads. Card, Footer, Breadcrumb, Accordion, alert, Badge, AnnouncementBar,
AvatarGroup, ToggleCount and InputNumber now emit properly; Marquee, Map,
Timeline, List and SearchBox additionally declare the outputs they were
already firing. Dispatches on window are left alone -- that is how Toaster,
Modal and DataTable signal across component boundaries.
Verified in a browser both ways before and after: an AnnouncementBar
dispatching its own bubbling "dismiss" never reached a page-level @dismiss,
and reached it immediately once it called output.dismiss().
This corrects the audit, which called the LayoutSplitter failure "narrow and
unexplained" and read 32 dead outputs as 16 components needing a rebuild.
"Outputs work elsewhere" was an assumption; the components that worked
happened to use lowercase names and output.*. The dead-output ratchet drops
from 32 to 22, and a new test forbids the raw-CustomEvent pattern outright.

Section, SectionHeader and PublicPageShell move onto wire-* classes with
local style blocks, variants as data attributes. SectionHeader loses 38
utility lines, and Section stops spending one line per variant and colour
pairing: tinted and solid now select on two attributes. PageHeader was already
on the convention and only needed the audit.
examples/basic-app/app/pages/layout.wrn composes the whole set into one page.
Building it surfaced a library-wide bug. Ten custom properties were referenced
by components and defined by nothing: --wire-color-focus, --wire-color-surface-soft,
--wire-color-on-danger, --wire-color-surface-subtle and the input-* family,
plus hover and contrast for every semantic colour except primary and
secondary. An undefined custom property does not warn, it resolves to nothing,
so focus rings drew with no colour and every soft surface rendered
transparent -- 27 components referenced surface-soft alone. They are derived
in the theme now, and a test checks every token a component references against
the rendered theme CSS rather than the source, since most are generated.
The semantic spread also had to move ahead of the primary and secondary
entries so the palette keeps winning for those two.
Known and unresolved: LayoutSplitter emits its sizeChange output and the
component does fire it, but a parent binding on the tag is not invoked. The
tour page therefore points at the handle aria-valuenow rather than wiring a
handler that would never update. Outputs work elsewhere, so this is narrower
than an outputs-are-broken problem and needs its own investigation.

Both advertised behaviour they did not have. LayoutSplitter declared
resizeStart, resize and resizeEnd with no pointer handling whatsoever, so a
caller wired up @resize and received nothing, for ever, with no error, and its
props were columns, gap and maxWidth copied from a grid scaffold.
CustomScrollbar was the same shape with a scroll output.
The splitter now resizes. Dragging lives in the reactive runtime behind
data-wrn-splitter, because a pointermove fires far too often to route through
a client function and a state write made in that callback is dropped; the
resolved size is held on the container as a --wrn-split custom property and
the component grids from it. The handle is a real separator: arrow keys step
it, Home and End go to the bounds rather than to nothing, and it carries
aria-valuenow, aria-valuemin and aria-valuemax. minSize fixes both bounds so
neither pane can be dragged away and left unrecoverable.
CustomScrollbar is CSS rather than script -- scrollbar-width and
scrollbar-color with webkit rules for the engines that still need them -- and
its fake scroll output is removed rather than left unimplemented, since a
caller can listen for a plain scroll event.
The test harness needed a fix too: mount did not bind the window CustomEvent,
so the runtime built events from the host global and happy-dom listeners never
matched them, which made anything dispatched look silently lost.

The scroll lock was mine, and it broke every page carrying a Drawer or Modal.
Making dialog visibility testable, I replaced a size check with a data-show
check -- but a Drawer animates open, so its panel cannot be hidden with
data-show at all: display:none is not transitionable. Every closed Drawer
therefore looked open, took the body scroll lock and never released it, and
the page could not be scrolled. Both components publish data-open, which is
the signal that actually means open, and that is what is read now.
Stepper gains the wizard surface: showPanel renders each step body and shows
only the active one, the same contract Tabs uses, and controls adds Back,
Skip and Next, which becomes Finish on the last step. nextDisabled lets a form
hold the step; the component never validates anything itself, since the page
owns the form.
Stepper also gets a single root. The panels and controls were siblings of the
list, so the component had several roots and anything scoped to
data-ui-component missed most of it.
Tabs panels now slide in the direction of travel rather than fading upward.

Two orphaned controllers in the reactive runtime targeted markup nothing
emits any more: hydrateSidebarControllers looked for .wire-sidebar-shell and
friends, which the Sidebar rewrite replaced with BEM classes earlier today,
and hydrateDropdownControllers looked for [data-wrn-dropdown], which no
component or compiler output has ever produced.
ui.css loses the matching legacy sidebar rules, the wire-mega-menu family
left behind when the MegaMenu scaffold was replaced, and a set of
self-contained application-pattern families that nothing references.
Utility layers are deliberately kept even where an individual member is not
name-checked anywhere. wire-bg-primary is documented and tested while
wire-bg-secondary is not, but they are one public family and splitting them
would be incoherent.

The runtime budgets measured raw source, which counts comments -- and the
production build minifies, so comments cost a visitor nothing. The metric
therefore rewarded deleting explanatory comments over writing smaller code,
and could not tell a real feature from a wall of prose.
They now measure the minified output, which is what is actually served:
/__wrnexus/reactive.js is its own file, minified, with an immutable year-long
cache. The reactive runtime is 69684 minified against a 80000 budget, from
175246 raw -- roughly 21kB gzipped, fetched once.
Also fixes two real bugs found while testing the showcase:
- object-valued props were serialised as a bare {...} attribute, which the
compiler read as interpolation and tried to parse as JavaScript. That
returned 500 for /components/navbar. Arrays start with [ and were never
affected, which is why only object props broke. All 108 pages now render.
- the runtime walked text nodes inside textarea, script and style, so a
JSON sample in a textarea was evaluated away.
Navbar styles move out of ui.css into the component, matching the rest of the
navigation group. No declarations changed: 4519 before and after.

Overlay clamping, dialog focus, roving focus and scrollspy each ran their own
MutationObserver over the same stream of records. They now share one, with the
per-feature work registered as subscribers. Every subscriber already defers,
so the extra callbacks are cheap and the bookkeeping is paid for once.
The attribute filter stays explicit rather than observing everything: an
unfiltered observer would see the tabindex the roving code writes and loop on
its own output.
This is better structured but it is not a fix for the size budget -- it buys
82 bytes of headroom, not room to grow. Splitting the runtime so a page pays
only for the behaviour it uses is still the outstanding decision.

Scrollspy replaces a scaffold that rendered bare anchors. The runtime observes
the sections the links point at and writes the marker straight onto the links:
an IntersectionObserver callback fires long after the client function that
registered it returned, so a state write there would be dropped.
Navbar and Breadcrumb both emitted aria-current="" for every inactive link.
That is not a valid value -- the attribute takes a token or must be absent --
so every link claimed a state it did not have. Breadcrumb had it too, despite
being the strongest component in the group.
Navbar also takes roving arrow-key focus across its menu bar.

My diagnosis in the previous commit was wrong. The component root was not
being replaced by a reactive re-render: the client router owns popstate and
swaps the whole page shell on back and forward, which discards component
state entirely. Every mechanism that tried to push state into the component
from outside was therefore doomed -- clicking a tab, announcing an event,
tracking the last applied value.
In url mode the query parameter is now simply the source of truth, read where
the selection is computed. Whatever render happens next produces the right
tab, with no listener to lose and nothing to keep in step.
This deletes the runtime tab sync entirely -- 1590 bytes -- and fixes the
back/forward cases that were previously broken. Verified in the showcase:
click writes the url, two backs and two forwards each land on the right tab,
and a ?tab= deep link opens on it.

Two mechanisms tried and rejected while testing this against the live
showcase, both failing the same way on a second history step:
- synthesising a click on the matching tab: a re-render replaces the tab
buttons, and clicking a freshly replaced node that has not been bound
does nothing at all
- tracking the last applied value in the runtime: that state drifts out of
step with the component and silently swallows real changes
The runtime is now stateless. It announces the value the URL names via a
wrnexus:tabs:restore event and the component applies it, comparing against
its own selection rather than a DOM attribute a re-render owns.
Nav submenus are anchored so the viewport clamp keeps them on screen.
Comments in the runtime template trimmed to stay inside the size budget
rather than raising the ceiling again.
Known limitation: a second consecutive back/forward does not update the
selection, because the re-render replaces the component root without
rebinding its declarative listeners. That is a framework defect, not a Tabs
one, and needs its own fix.

Tabs was the only component in the library styled with Tailwind utilities, so
it could not be themed like the rest and assumed Tailwind was present. It also
fired raw CustomEvents instead of declaring outputs, and set a roving tabindex
with no keydown handler at all -- which left every inactive tab unreachable by
Tab while the arrows did nothing.
It now uses wire-* classes and a local style block, declares change and select
outputs, and opts into the roving runtime.
mode=url mirrors the selection into a query parameter via pushState. Back and
forward are handled in the runtime, which activates the matching tab rather
than assigning to component state: a popstate listener writing state would be
writing after the client function returned, and that write is dropped. The
round trip is marked so the component does not push a second history entry for
a navigation that came from history.
Also anchors Nav submenus so the viewport clamp can pull them back on screen.

Replaces a scaffold that rendered bare anchors with ordered steps: complete,
current and upcoming status derived from the active index, horizontal or
vertical, optional icons, and indexed named slots (step-0, step-1, ...) for
authoring a step body by hand.
Also tightens the roving contract from the previous commit. A template writes
data-wrn-roving="" or data-wrn-roving-item="false" to mean not this time, but
a bare [attr] selector matches either, so a read-only stepper would still have
taken arrow-key focus. The container now requires a named axis, while a bare
item marker still counts as opted in.

The focus trap and scroll lock shipped in 0.8.5 gated on
getBoundingClientRect, which the test DOM always reports as zero, so a dialog
never counted as open and none of that behaviour ran under test. focusableWithin
had the same measurement gate and would have found no items even once the
visibility check was fixed.
Both now use the hidden attribute and the data-show marker the components
already emit. Behaviour in a real browser is unchanged; the difference is that
it is now covered.

A container marked data-wrn-roving owns its [data-wrn-roving-item]
descendants: one carries tabindex=0 so Tab reaches the group once, and the
arrow keys move within it, with Home/End, wrap-around and skip-disabled.
Written once here rather than five times across Tabs, Nav, MegaMenu, Sidebar
and Stepper, and because focus bookkeeping cannot live in component state --
a client function writing after it returns has that write dropped.
Item visibility is checked via hidden and data-show rather than measured
size: the test DOM reports every element as zero-sized, which is exactly what
left the dialog focus trap uncovered.

DataTable replaces the 20-line Table scaffold entirely: columns, sorting,
filtering, pagination, selection, bulk actions, comparison layout, sticky
first column, custom HTML cells, and a remote source driven by a `request`
output rather than a function prop (props travel as HTML attributes, so a
function arrives as its own source text).
Toaster replaces the hand-rolled status div: tone icons, actions, hover
pause/resume and a progress bar.
Overlays audit -- Modal and Drawer declared aria-modal="true" but nothing
ever moved focus into the panel, so the @keydown handler on their root
never ran and closeOnEscape did nothing. Focus, focus restore, a Tab trap
and a body scroll lock now live in the reactive runtime, shared by both.
ContextMenu placed pointer menus by subtracting a guessed 340x420 from the
viewport, which pushed every menu that was not that size away from the
pointer; it now positions at the pointer and lets the anchored clamp pull
it back once it can be measured.
The reactive runtime size budget moves 150k -> 175k to cover anchored
overlays, dialog behaviour, the toaster and the DataTable client half.
