Route all rendering through OCaml bridge — render_to_html no longer uses
Python async_eval. Fix register_components to parse &key params and &rest
children from defcomp forms. Remove all dead sx_ref.py imports.
Epoch protocol (prevents pipe desync):
- Every command prefixed with (epoch N), all responses tagged with epoch
- Both sides discard stale-epoch messages — desync structurally impossible
- OCaml main loop discards stale io-responses between commands
Consolidate scope primitives into sx_scope.ml:
- Single source of truth for scope-push!/pop!/peek, collect!/collected,
emit!/emitted, context, and 12 other scope operations
- Removes duplicate registrations from sx_server.ml (including bugs where
scope-emit! and clear-collected! were registered twice with different impls)
- Bind scope prims into env so JIT VM finds them via OP_GLOBAL_GET
JIT VM fixes:
- Trampoline thunks before passing args to CALL_PRIM
- as_list resolves thunks via _sx_trampoline_fn
- len handles all value types (Bool, Number, RawHTML, SxExpr, Spread, etc.)
Other fixes:
- ~cssx/tw signature: (tokens) → (&key tokens) to match callers
- Minimal Python evaluator in html.py for sync sx() Jinja function
- Python scope primitive stubs (thread-local) for non-OCaml paths
- Reader macro resolution via OcamlSync instead of sx_ref.py

Move defhandler/defquery/defaction/defpage/defrelation from hardcoded
evaluator dispatch to web/web-forms.sx extension module, registered via
register-special-form!. Adapters updated to use definition-form? and
dynamically extended form-name lists.
Fix modifier-key clicks (ctrl-click → new tab) in three click handlers:
bindBoostLink, bindClientRouteClick, and orchestration.sx bind-event.
Add event-modifier-key? primitive (eventModifierKey_p for transpiler).
Fix CSSX SSR: ~cssx/flush no longer drains the collected bucket on the
server, so the shell template correctly emits CSSX rules in <head>.
Add missing server-side DOM stubs (create-text-node, dom-append, etc.)
and SSR passthrough for portal/error-boundary/promise-delayed.
Passive event listeners for touch/wheel/scroll to fix touchpad scrolling.
97/97 Playwright demo tests + 4/4 isomorphic SSR tests pass.

~cssx/flush now appends rules to <style id="sx-css"> in <head>
instead of creating ephemeral inline <style> tags that get morphed
away during SPA navigation. Rules accumulate across navigations.
Future: reference-count rules and remove when no elements use them.

Three bugs in aser-expand-component (adapter-sx.sx):
- Keyword values were eval'd (eval-expr can't handle <>, HTML tags);
now asered, matching the aser's rendering capabilities
- Missing default nil binding for unset &key params (caused
"Undefined symbol" errors for optional params like header-rows)
- aserCall string-quoted keyword values that were already serialized
SX — now inlines values starting with "(" directly
Server-affinity annotations for layout/nav shells:
- ~shared:layout/app-body, ~shared:layout/oob-sx — page structure
- ~layouts/nav-sibling-row, ~layouts/nav-children — server-side data
- ~layouts/doc already had :affinity :server
- ~cssx/flush marked :affinity :client (browser-only state)
Navigation fix: restore oob_page_sx wrapper for HTMX responses
so #main-panel section exists for sx-select/sx-swap targeting.
OCaml bridge: lazy page helper injection into kernel via IO proxy
(define name (fn (...) (helper "name" ...))) — enables aser_slot
to evaluate highlight/component-source etc. via coroutine bridge.
Playwright tests: added pageerror listener to test_no_console_errors,
new test_navigate_from_home_to_geography for HTMX nav regression.

adapter-dom.sx: if/when/cond reactive paths now check whether
initial-result is a spread. If so, return it directly — spreads
aren't DOM nodes and can't be appended to fragments. This lets
any spread-returning component (like ~cssx/tw) work inside islands
without the spread being silently dropped.
cssx.sx: revert make-spread workaround — the root cause is now
fixed in the adapter. ~cssx/tw can use a natural top-level if.

deps.sx: scan island bodies for component deps (was only scanning
"component" and "macro", missing "island" type). This ensures
~cssx/tw and its dependencies are sent to the client for islands.
cssx.sx: move if inside make-spread arg so it's evaluated by
eval-expr (no reactive wrapping) instead of render-to-dom which
applies reactive-if inside island scope, converting the spread
into a fragment and losing the class attrs.
Added island dep tests at 3 levels: test-deps.sx (spec),
test_deps.py (Python), test_parity.py (ref vs fallback).
sx-browser.js: temporary debug logging at spread detection points.

New SX primitives for child-to-parent communication in the render tree:
- spread type: make-spread, spread?, spread-attrs — child injects attrs
onto parent element (class joins with space, style with semicolon)
- collect!/collected/clear-collected! — render-time accumulation with
dedup into named buckets
~cssx/tw is now a proper defcomp returning a spread value instead of a
macro wrapping children. ~cssx/flush reads collected "cssx" rules and
emits a single <style data-cssx> tag.
All four render adapters (html, async, dom, aser) handle spread values.
Both bootstraps (Python + JS) regenerated. Also fixes length→len in
cssx.sx (length was never a registered primitive).

Replace the three-layer cssx system (macro + value functions + class
components) with a single token resolver. Tokens like "bg-yellow-199",
"hover:bg-rose-500", "md:text-xl" are parsed into CSS declarations.
Two delivery mechanisms, same token format:
- tw() function: returns inline style string for :style
- ~cssx/tw macro: injects JIT class + <style> onto first child element
The resolver handles: colours (21 names, any shade 0-950), spacing,
typography, display, max-width, rounded, opacity, w/h, gap, text
decoration, cursor, overflow, transitions. States (hover/focus/active)
and responsive breakpoints (sm/md/lg/xl/2xl) for class-based usage.
Next step: replace macro/function approach with spec-level primitives
(defcontext/provide/context + spread) so ~cssx/tw becomes a proper
component returning spread values, with rules collected via context.

Islands survive hypermedia swaps: morph-node skips hydrated
data-sx-island elements when the same island exists in new content.
dispose-islands-in skips hydrated islands to prevent premature cleanup.
- @client directive: .sx files marked ;; @client send define forms to browser
- CSSX client-side: cssxgroup renamed (no hyphen) to avoid isRenderExpr
matching it as a custom element — was producing [object HTMLElement]
- Island wrappers: div→span to avoid block-in-inline HTML parse breakage
- ~sx-header is now a defisland with inline reactive colour cycling
- bootstrap_js.py defaults output to shared/static/scripts/sx-browser.js
- Deleted stale sx-ref.js (sx-browser.js is the canonical browser build)
- Hegelian Synthesis essay: dialectic of hypertext and reactivity
- component-source helper handles Island types for docs pretty-printing
