Parser: skip unit suffix when next ident is a comparison keyword
(starts, ends, contains, matches, is, does, in, precedes, follows).
Fixes "123 starts with '12'" returning "123starts" instead of true.
eval-hs: use hs-compile directly instead of hs-to-sx-from-source with
"return " prefix, which was causing the parser to consume the comparison
as a string suffix.

Replace WebTransport-only design with three-transport model:
- Browser↔server: WebSocket (works today, no infrastructure changes)
- Browser↔browser: WebRTC data channels (true P2P, NAT traversal)
- Server↔server: HTTP federation (existing sx-pub)
Home nodes relay WebRTC signaling. Reliable channels for chat/components,
unreliable channels for game state/cursor positions. Transport-agnostic
protocol layer — upgrade to WebTransport later with zero SX changes.

Phase 2d: shared-signal primitive — local signal writes propagate to
peers via WebTransport rooms. Same deref/reset!/swap! API, networking
invisible to the reactive layer. LWW default, CRDT opt-in.

Two bugs caused code blocks to render empty across the site:
1. ~docs/code component had parameter named `code` which collided with
the HTML <code> tag name. Renamed to `src` and updated all 57
callers. Added font-mono class for explicit monospace.
2. Batched IO dispatch in ocaml_bridge.py only skipped one leading
number (batch ID) but the format has two (epoch + ID):
(io-request EPOCH ID "name" args...). Changed to skip all leading
numbers so the string name is correctly found. This fixes highlight
and other batchable helpers returning empty results.

Three issues in the stepper island's client-side rendering:
1. do-step used eval-expr with empty env for ~cssx/tw spreads — component
not found, result leaked as [object Object]. Fixed: call ~cssx/tw
directly (in scope from island env) with trampoline.
2. steps-to-preview excluded spreads — SSR preview had no styling.
Fixed: include spreads in the tree so both SSR and client render
with CSSX classes.
3. build-children used named let (let loop ...) which produces
unresolved Thunks in render mode due to the named-let compiler
desugaring interacting with the render/eval boundary. Fixed:
rewrote as plain recursive function bc-loop avoiding named let.

provide/context and scope/emit!/emitted now use CEK continuation
frames instead of an imperative global stack. Scope state is part
of the continuation — captured by shift, restored by k invocation.
New frame types:
- ProvideFrame: holds name + value, consumed when body completes
- ScopeAccFrame: holds name + mutable emitted list
New CEK special forms:
- context: walks kont for nearest ProvideFrame, returns value
- emit!: walks kont for nearest ScopeAccFrame, appends to emitted
- emitted: walks kont for nearest ScopeAccFrame, returns list
Kont walkers: kont-find-provide, kont-find-scope-acc
This fixes the last 2 test failures:
- provide survives resume: scope captured by shift, restored by k
- scope and emit across shift: accumulator preserved in continuation

Continuations are now multi-shot — k can be invoked multiple times.
Each invocation runs the captured frames via nested cek-run and
returns the result to the caller's continuation.
Fix: continue-with-call runs ONLY the captured delimited frames
(not rest-kont), so the continuation terminates and returns rather
than escaping to the outer program.
Fixed 4 continuation tests:
- shift with multiple invokes: (list (k 10) (k 20)) → (11 21)
- k returned from reset: continuation callable after escaping
- invoke k multiple times: same k reusable
- k in data structure: store in list, retrieve, invoke
Remaining 2 failures: scope/provide across shift boundaries.
These need scope state tracked in frames (not imperative push/pop).

Higher-order forms (map, filter, reduce, some, every?, for-each,
map-indexed) now evaluate their arguments via CEK frames instead
of nested trampoline(eval-expr(...)) calls.
Added HoSetupFrame — staged evaluation of HO form arguments.
When all args are evaluated, ho-setup-dispatch sets up the
iteration frame. This keeps a single linear CEK continuation
chain instead of spawning nested CEK instances.
14 nested eval-expr calls eliminated (39 → 25 remaining).
The remaining 25 are in delegate functions (sf-letrec, sf-scope,
parse-keyword-args, qq-expand, etc.) called infrequently.
All tests unchanged: JS 747/747, Full 864/870, Python 679/679.

The depth axis is done — CEK (Layer 0) through patterns (Layer 4) are
all specced, bootstrapped, and tested. Rewrite the plan to reflect
reality and reframe the next steps as validation (serialization,
stepping debugger, content-addressed computation) before building
superstructure (concurrent CEK, linear effects).

Replace hand-written serialize/sx_serialize/sx_parse in Python with
spec-derived versions from parser.sx. Add parser as a Python adapter
alongside html/sx/async — all 48 parser spec tests pass.
Add reactive runtime plan to sx-docs: 7 feature layers (ref, foreign
FFI, state machines, commands with undo/redo, render loops, keyed
lists, client-first app shell) — zero new platform primitives.

test-cek-reactive.sx: 9 tests across 4 suites — deref pass-through,
signal without reactive-reset, reactive-reset shift with continuation
capture, scope disposal cleanup. run_cek_reactive_tests.py: new runner
loading signals+frames+cek. Both test runners override sx_ref.eval_expr
back to tree-walk so interpreted .sx uses tree-walk internally.
Plan page added to sx-docs.

all adapters (async, dom, html, sx) and platform implementations

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/*,
