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).

Add url-to-expr, auto-quote-unknowns, prepare-url-expr to router.sx —
the canonical URL-to-expression pipeline. Dots→spaces, parse, then
auto-quote unknown symbols as strings (slugs). The same spec serves
both server (Python) and client (JS) route handling.
- router.sx: three new pure functions for URL evaluation
- bootstrap_py.py: auto-include router module with html adapter
- platform_js.py: export urlToExpr/autoQuoteUnknowns/prepareUrlExpr
- sx_router.py: replace hand-written auto_quote_slugs with bootstrapped
prepare_url_expr — delete ~50 lines of hardcoded function name sets
- Rebootstrap sx_ref.py (4331 lines) and sx-browser.js

New platform_js primitives for direct DOM property/method access and
cross-origin iframe communication. Service worker static cache bumped
to v2 to flush stale assets. Removed experimental video embed from
header island, routes, and home page.

New hierarchy: Geography (Reactive Islands, Hypermedia Lakes, Marshes,
Isomorphism), Language (Docs, Specs, Bootstrappers, Testing),
Applications (CSSX, Protocols), Etc (Essays, Philosophy, Plans).
All routes updated to match: /reactive/* → /geography/reactive/*,
/docs/* → /language/docs/*, /essays/* → /etc/essays/*, etc.
Updates nav-data.sx, all defpage routes, API endpoints, internal links
across 43 files. Enhanced find-nav-match for nested group resolution.
Also includes: page-helpers-demo sf-total fix (reduce instead of set!),
rebootstrapped sx-browser.js and sx_ref.py, defensive slice/rest guards.

Two bugs fixed:
1. process-bindings used merge(env) which returns {} for Env objects
(Env is not a dict subclass). Changed to env-extend in render.sx
and adapter-async.sx. This caused "Undefined symbol: theme" etc.
2. async-aser-eval-call passed evaled-args list to async-invoke(&rest),
double-wrapping it. Changed to inline apply + coroutine check.
Also: bootstrap define-async into sx_ref.py (Phase 6), replace ~1000 LOC
hand-written async_eval_ref.py with 24-line thin re-export shim.
Test runner now uses Env (not flat dict) for render envs to catch scope bugs.
8 new regression tests (4 scope chain, 2 native callable arity, 2 render).

- Add page-helpers-demo page with defisland ~demo-client-runner (pure SX,
zero JS files) showing spec functions running on both server and client
- Fix _aser_component children serialization: flatten list results from map
instead of serialize(list) which wraps in parens creating ((div ...) ...)
that re-parses as invalid function call. Fixed in adapter-async.sx spec
and async_eval_ref.py
- Switch _eval_slot to use async_eval_ref.py when SX_USE_REF=1 (was
hardcoded to async_eval.py)
- Add Island type support to async_eval_ref.py: import, SSR rendering,
aser dispatch, thread-first, defisland in _ASER_FORMS
- Add server affinity check: components with :affinity :server expand
even when _expand_components is False
- Add diagnostic _aser_stack context to EvalError messages
- New spec files: adapter-async.sx, page-helpers.sx, platform_js.py
- Bootstrappers: page-helpers module support, performance.now() timing
- 0-arity lambda event handler fix in adapter-dom.sx
