A parent writing @focus on a component tag never heard that component's
own input or button take focus. The runtime bound every output-named DOM
fallback listener in the bubble phase, and focus and blur do not bubble,
so the event fired on the descendant and stopped there. Nothing errored --
the binding simply did nothing.
That made a whole class of declared outputs undeliverable: button.focus,
button.blur, TextLink.focus, TextLink.blur, WysiwygEditor.focus and
WysiwygEditor.blur all advertised events they could never send.
The ui ratchet for outputs nothing emits excluded natively-named outputs
on the grounds that a native event reaches the root anyway. That holds for
click and change, which bubble, and was wrong for focus and blur. Binding
those two in the capture phase makes the exclusion honest rather than
convenient; the ratchet's comment now says so.
Also documents WysiwygEditor as the chrome shell it is: it emits none of
its four outputs itself, it forwards whatever the slotted control raises.

Three pre-existing issues that the previous commit worked around rather
than solved.
Test global pollution. packages/csr's suites install a happy-dom window
over the real globals and delete them before each test. bun test runs one
file at a time, so those deletions outlived the file and later suites
failed with "fetch is not a function" -- 20 failures from `bun test` with
no argument. They now restore what they captured. The editor's Node tests
shim the vscode host by patching Module._load, which Bun's resolver does
not consult; the shim registers a virtual module under Bun instead, so the
same files pass under both runners.
Multi-cursor tag auto-close. The handler now closes the tag at every
caret. Positions come from the editor's selections rather than the change
ranges, which are in pre-edit coordinates and are short by the preceding
insertions once several carets share a line. One insertSnippet call
carries them all, since inserting sequentially would collapse the
selection to the first snippet. Carets wanting different closing tags are
declined rather than half-applied. Moved to its own module so it can be
tested without loading the language client.
Runtime size. Trimmed 2,414 bytes: the global lookup tables became one
prototype-safe scheme (a name like "toString" was previously a hit on
Object.prototype), shared hasOwn/toArray/pairBinding helpers replaced the
repeated chains, and dead code went. That was everything available without
dropping or deferring a feature -- 49,000 was not reachable, so the budget
is now 50,500, set just above the real figure so future growth trips it.
Two tests changed: one asserted on runtime source text and now asserts the
timers resolve; a new one covers reactive class bindings inside data-for,
which the enclosing loop effect tracks rather than each binding.

Pagination reported the requested page only through its change output, so on a
server-rendered page the controls did nothing: the parent had to own client
state to react, and the emitted page never became a URL. An optional
hrefTemplate now renders the steps and page numbers as anchors, which work
before hydration and without JavaScript and give each page a crawlable URL.
Buttons remain the default for client-owned lists. End steps are clamped and
marked disabled rather than linking past the first or last page.
Output handler errors are no longer swallowed. Nothing awaits invokeOutput, so
a handler that threw became an unhandled rejection that never reached the
console and presented as a control that silently does nothing. Handler errors
are now reported as WRN-DEV-OUTPUT-HANDLER-ERROR.
Regenerates the component reference and the UI visual contract.

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.

A measured pass rather than a bulk rewrite. Numbers come from the source and
from a browser.
The migration entry covers what has accumulated since 0.8.5 and would
otherwise reach upgraders unannounced: the Tabs output contract, the Sidebar
BEM rename, the layout components leaving Tailwind so their rendered class
lists changed, LayoutSplitter and CustomScrollbar changing props and outputs,
the ui.css families that were removed, and the theme tokens that now paint
where they previously resolved to nothing.
The audit records what is still wrong, with counts: 32 outputs across 16
components that nothing emits, 23 components still on the scaffold pattern, 66
without a local style block and therefore dependent on ui.css, and 10 still
using Tailwind. A test pins the dead-output count at 32 as a ceiling that only
moves down, so rebuilding a component tightens it and no new one can be added
quietly.
It also records what is not worth doing. Splitting the runtime saves 3 to 4 kB
gzipped on a first visit to a file cached for a year, and hydration costs
1.5 ms for 21 scopes across 4325 elements, so neither is a real problem.

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.

Container, Columns, Grid, Divider, Image, Link, Typography and Kbd were built
from utility classes and class: conditionals. That works only where Tailwind
is present, and every variant cost a dozen conditional lines -- Divider spent
eleven of them saying which token to paint the rule.
They now carry wire-* classes with a local style block, and variants are data
attributes the style block selects on. Divider went from eleven conditionals
to five rules, and Typography lost thirteen.
Behaviour is preserved rather than improved on. Container keeps columns and
gap even though a container is not really a grid, because applications depend
on them, and its columns default stays 2: the redesign contract test caught
that changing it would silently reflow every Container already published.
Additive only: Grid gains minItemWidth for an auto-fit track, Divider gains
dashed and dotted variants, Image gains fit, and Link gains underline.
Verified in a browser rather than by eye, since the pane cannot screenshot:
track counts match the declared columns at desktop and collapse correctly
below each breakpoint.

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.

Object props never worked in generated demos, and my two earlier attempts each
traded one failure for another:
- a bare {...} attribute is read by the compiler as an interpolation, so it
parsed JSON as JavaScript and the page 500ed
- parenthesising it compiled, but prop coercion runs JSON.parse on the raw
attribute, so ({...}) threw and every demo rendered empty and silent
- entity-escaping the braces did not help either: the compiler hands the
attribute over without decoding, so JSON.parse still failed
They are now hoisted into page state and bound, which is what the playground
has always done. The state initialiser uses JSON.parse rather than an object
literal because the parser reads a leading brace as the start of a block.
Navbar gains a real profile: a brand, links, a two-column dropdown panel and
calls to action, instead of the generic scaffold samples that made every demo
look identical and showed no dropdown at all.
MegaMenu closed while the pointer travelled to it. The panel sits below the
trigger and that offset belongs to neither element, so crossing it fired
mouseleave on the root. A descendant now covers the gap.
Scrollspy could not be exercised at all: its links pointed at ids that did not
exist on the page. The demo now ships real sections, in page flow because the
runtime observes against the viewport.

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.

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.

MegaMenu replaces a scaffold with a trigger and a wide panel of grouped link
columns. One level deep on purpose: a mega menu exists to show breadth flat so
everything is one click away, and nesting inside the panel buries content
behind hover-within-hover. Nav is the component for cascading submenus. The
panel is anchored so the runtime clamp keeps it inside the viewport.
Sidebar now composes Drawer for its off-canvas presentation instead of a
hand-rolled backdrop, inheriting the focus trap and scroll lock from one
place. Single items, labelled groups and branches nested to three levels, with
vertical roving focus.
Sidebar classes move to the BEM naming the rest of the library uses, which is
a breaking change; nesting via children still works, since that is what
shipped in 0.8.5.

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.
