A route mounting an island ships JavaScript, so reporting it as zero-JS
static would make the framework's performance accounting wrong.
Adds a separate needsIslandRuntime flag rather than reusing
needsClientRuntime: an island needs the island runtime, not WRNexus's
reactive runtime, and conflating them would ship the wrong bundle.
analyzeRuntimeRequirements takes island presence as an optional second
argument, so existing callers are unaffected.

Adds /__wrnexus/islands.js (the bootstrap) and the /__wrnexus/island/
prefix (mount runtime, island bundles, shared chunks) to all three
serving paths.
Dev reuses the browserArtifactPaths registry pattern from pipeline.ts.
Prod mirrors the clientModulesDir handler, including its filename
allowlist, so island names cannot escape the output directory.
The bootstrap is inert without a data-wrn-island marker, so island-free
pages still download nothing.

splitting:true keeps React in one shared chunk so a page with several
islands does not ship react-dom repeatedly.
Island .tsx is compiled against React's JSX runtime via a Bun onLoad
plugin. The repo's root tsconfig sets jsxImportSource to @wrnexus/core,
so islands would otherwise compile to the HTML-string renderer and never
mount. A @jsxImportSource pragma only affects the file carrying it, so
injecting one into the generated entry is not enough — the injection has
to happen per source file. App-authored islands stay plain .tsx.
The JSX test asserts built output rather than generated entry text,
because the entry-text assertion passed while the mechanism did not work.

Mounts markers with client:only/load/visible/idle, and disposes roots on
route change so React roots, detached DOM, and store subscriptions do
not leak across client-side navigation.
Bundle load failures and malformed props JSON degrade to a warning and
leave the server markup intact rather than taking down the page.

A crashed island renders its error in dev and nothing in prod, leaving
the surrounding server-rendered page intact.
Island .tsx sources carry an explicit @jsxImportSource react pragma: the
repo's root tsconfig points jsxImportSource at @wrnexus/core, so without
it island JSX compiles to WRNexus's string renderer instead of React
elements.
Tests render on the client via createRoot rather than a server renderer,
because React error boundaries do not engage during SSR — and islands
are client-only regardless.

.wrn keeps resolution priority so existing components are unaffected
when a .tsx file shares their name.

Emits the data-wrn-island placeholder, parses client:* strategies, and
rejects non-serializable props at compile time via WRN-ISLAND-PROPS so
the serialization boundary fails where it is cheapest to fix.
Island names become URL path segments when the browser fetches the
island bundle, so they are validated with core's existing
isSafeIslandName rather than relying on escaping alone. This adds
@wrnexus/core to the compiler's dependencies; core has no dependencies
of its own, so no cycle is introduced.

Resolves WRNexus stores from inside islands, reading through the cached
snapshot so React sees a stable reference. Unknown store names throw
with the list of registered stores rather than failing opaquely.

useSyncExternalStore requires getSnapshot to return an identical
reference when unchanged; @wrnexus/store's readonlySnapshot returns a
fresh clone per call. The cache lives here rather than in the store
package so existing consumers are untouched.
createSelectorCache takes an optional equality function: the Object.is
default can never stabilize a selector that allocates, which is the
usual source of infinite re-renders.

check-component-imports scans sources for <Component> tags and requires each to
be imported. The explanatory comment added with the prose-scoping fix wrote
<Blockquote> literally, so the checker demanded an import for a component the
file never renders. Naming it without angle brackets keeps the explanation and
clears the gate.

hasExecutableSql returns as soon as it meets a quote character, so the quote
variable was assigned and never read: the `if (quote)` branch could never run.
eslint reported it as a useless assignment and the error blocks the release
gate on main. Removing the variable and the unreachable branch keeps behaviour
identical, since encountering a quote already means the SQL is executable.
Also drops an eslint-disable directive in csr's output error reporter that
suppressed nothing.

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.

Typography styled every descendant element, including those inside nested UI
components. A <Blockquote variant="bordered"> placed inside <Typography> drew
two left borders: its own, plus the one these prose rules apply to any
<blockquote>. The same leak applied to headings, links, lists and code.
Prose rules now exclude the subtree of any nested `.wrn-component`, so they
style raw markup only. The exclusion sits inside :where() so specificity stays
at zero and applications can still override these rules with a plain class.
