- Effect and computed auto-register disposers with island scope via
register-in-scope; dispose-islands-in called before every swap point
(orchestration.sx) to clean up intervals/subscriptions on navigation.
- Map + deref inside islands auto-upgrades to reactive-list for signal-
bound list rendering. Demo island with add/remove items.
- New :bind attribute for two-way signal-input binding (text, checkbox,
radio, textarea, select). bind-input in adapter-dom.sx handles both
signal→element (effect) and element→signal (event listener).
- Phase 2 plan page at /reactive-islands/phase2 covering input binding,
keyed reconciliation, reactive class/style, refs, portals, error
boundaries, suspense, and transitions.
- Updated status tables in overview and plan pages.
- Fixed stopwatch reset (fn body needs do wrapper for multiple exprs).

Three bugs prevented islands from working during SX wire navigation:
1. components_for_request() only bundled Component and Macro defs, not
Island defs — client never received defisland definitions during
navigation (components_for_page for initial HTML shell was correct).
2. hydrate-island used morph-children which can't transfer addEventListener
event handlers from freshly rendered DOM to existing nodes. Changed to
clear+append so reactive DOM with live signal subscriptions is inserted
directly.
3. asyncRenderToDom (client-side async page eval) checked _component but
not _island on ~-prefixed names — islands fell through to generic eval
which failed. Now delegates to renderDomIsland.
4. setInterval_/setTimeout_ passed SX Lambda objects directly to native
timers. JS coerced them to "[object Object]" and tried to eval as code,
causing "missing ] after element list". Added _wrapSxFn to convert SX
lambdas to JS functions before passing to timers.

- signals.sx: fix has? → has-key?, add def-store/use-store/clear-stores
(L3 named stores), emit-event/on-event/bridge-event (event bridge)
- boot.sx: add sx-hydrate-islands, hydrate-island, dispose-island
for client-side island hydration from SSR output
- bootstrap_js.py: add RENAMES, platform fns (domListen, eventDetail,
domGetData, jsonParse), public API exports for all new functions
- bootstrap_py.py: add RENAMES, server-side no-op stubs for DOM events
- Regenerate sx-ref.js (with boot adapter) and sx_ref.py
- Update reactive-islands status: hydration, stores, bridge all spec'd

The entire parallel CSS system (StyleValue type, style dictionary,
keyword atom resolver, content-addressed class generation, runtime
CSS injection, localStorage caching) was built but never adopted —
the codebase already uses :class strings with defcomp components
for all styling. Remove ~3,000 lines of unused infrastructure.
Deleted:
- cssx.sx spec module (317 lines)
- style_dict.py (782 lines) and style_resolver.py (254 lines)
- StyleValue type, defkeyframes special form, build-keyframes platform fn
- Style dict JSON delivery (<script type="text/sx-styles">), cookies, localStorage
- css/merge-styles primitives, inject-style-value, fnv1a-hash platform interface
Simplified:
- defstyle now binds any value (string, function) — no StyleValue type needed
- render-attrs no longer special-cases :style StyleValue → class conversion
- Boot sequence skips style dict init step
Preserved:
- tw.css parsing + CSS class delivery (SX-Css headers, <style id="sx-css">)
- All component infrastructure (defcomp, caching, bundling, deps)
- defstyle as a binding form for reusable class strings

parse() returns a list of expressions. resolveSuspense was passing the
entire array to renderToDom, which interpreted [(<> ...)] as a call
expression ((<> ...)) — causing "Not callable: {}". Now iterates
each expression individually, matching the public render() API.

Streaming resolve scripts arrive after boot, so any extra component
defs sent as <script type="text/sx"> tags weren't being loaded.
Fix in the spec (boot.sx): call (process-sx-scripts nil) at the
start of resolve-suspense so late-arriving component defs are
available in componentEnv before rendering.

Server streams HTML shell with ~suspense placeholders immediately,
then sends resolution <script> chunks as async IO completes. Browser
renders loading skeletons instantly, replacing them with real content
as data arrives via __sxResolve().
- defpage :stream true opts pages into streaming response
- ~suspense component renders fallback with data-suspense attr
- resolve-suspense in boot.sx (spec) + bootstrapped to sx-browser.js
- __sxPending queue handles resolution before sx-browser.js loads
- execute_page_streaming() async generator with concurrent IO tasks
- Streaming demo page at /isomorphism/streaming with 1.5s simulated delay

Replace hardcoded IO primitive lists on both client and server with
data-driven registration. Page registry entries carry :io-deps (list
of IO primitive names) instead of :has-io boolean. Client registers
proxied IO on demand per page via registerIoDeps(). Server builds
allowlist from component analysis.

Wire async rendering into client-side routing: pages whose component
trees reference IO primitives (highlight, current-user, etc.) now
render client-side via Promise-aware asyncRenderToDom. IO calls proxy
through /sx/io/<name> endpoint, which falls back to page helpers.
- Add has-io flag to page registry entries (helpers.py)
- Remove IO purity filter — include IO-dependent components in bundles
- Extend try-client-route with 4 paths: pure, data, IO, data+IO
- Convert tryAsyncEvalContent to callback style, add platform mapping
- IO proxy falls back to page helpers (highlight works via proxy)
- Demo page: /isomorphism/async-io with inline highlight calls

The data-mount="body" script replaces the entire body content,
destroying the <script type="text/sx-pages"> tag. Moving
processPageScripts before processSxScripts ensures the page
registry is read before the body is replaced.

Server-side: log page count, output size, and first 200 chars in _build_pages_sx.
Client-side: log script tag count, text length, parsed entry count in processPageScripts.
Helps diagnose why pages: 0 routes loaded.

Shows "pages: N routes loaded" at startup and
"sx:route no match (N routes) /path" when no route matches,
so we can see if routes loaded and why matching fails.

boot-init prints SX_VERSION (build timestamp) to console on startup.
tryClientRoute logs why it falls through: has-data, no content, eval
failed, #main-panel not found. tryEvalContent logs the actual error.
Added logWarn platform function.
