- Rename /reactive-islands/ → /reactive/, /reference/ → /hypermedia/reference/,
/examples/ → /hypermedia/examples/ across all .sx and .py files
- Add 404 error page (not-found.sx) working on both server refresh and
client-side SX navigation via orchestration.sx error response handling
- Add trailing slash redirect (GET only, excludes /api/, /static/, /internal/)
- Remove blue sky-500 header bar from SX docs layout (conditional on header-rows)
- Fix 405 on API endpoints from trailing slash redirect hitting POST/PUT/DELETE
- Fix client-side 404: orchestration.sx now swaps error response content
instead of silently dropping it
- Add new plan files and home page component

Lake tag (lake :id "name" children...) creates server-morphable slots
within islands. During morph, the engine enters hydrated islands and
updates data-sx-lake elements by ID while preserving surrounding
reactive DOM (signals, effects, event listeners).
Specced in .sx, bootstrapped to JS and Python:
- adapter-dom.sx: render-dom-lake, reactive-attr marks data-sx-reactive-attrs
- adapter-html.sx: render-html-lake SSR output
- adapter-sx.sx: lake serialized in wire format
- engine.sx: morph-island-children (lake-by-ID matching),
sync-attrs skips reactive attributes
- ~sx-header uses lakes for logo and copyright
- Hegelian essay updated with lake code example
Also includes: lambda nil-padding for missing args, page env ordering fix

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

7c: Client data cache management via element attributes
(sx-cache-invalidate) and response headers (SX-Cache-Invalidate,
SX-Cache-Update). Programmatic API: invalidate-page-cache,
invalidate-all-page-cache, update-page-cache.
7d: Service Worker (sx-sw.js) with IndexedDB for offline-capable
data caching. Network-first for /sx/data/ and /sx/io/, stale-while-
revalidate for /static/. Cache invalidation propagates from
in-memory cache to SW via postMessage.

engine.sx now contains only pure logic: parsing, morph, swap, headers,
retry, target resolution, etc. orchestration.sx contains the browser
wiring: request execution, trigger binding, SSE, boost, post-swap
lifecycle, and init. Dependency is one-way: orchestration → engine.
Bootstrap compiler gains "orchestration" as a separate adapter with
deps on engine+dom. Engine-only builds get morph/swap without the
full browser runtime.

Split monolithic render.sx into core (tag registries, shared utils) plus
four adapter .sx files: adapter-html (server HTML strings), adapter-sx
(SX wire format), adapter-dom (browser DOM nodes), and engine (SxEngine
triggers, morphing, swaps). All adapters written in s-expressions with
platform interface declarations for JS bridge functions.
Bootstrap compiler now accepts --adapters flag to emit targeted builds:
-a html → server-only (1108 lines)
-a dom,engine → browser-only (1634 lines)
-a html,sx → server with SX wire (1169 lines)
(default) → all adapters (1800 lines)
Fixes: keyword arg i-counter desync in reduce across all adapters,
render-aware special forms (let/if/when/cond/map) in HTML adapter,
component children double-escaping, ~prefixed macro dispatch.
