- CLAUDE.md: add SX rendering pipeline overview, service sx/ vs sxc/
convention, dev container mount convention
- docker-compose.dev.yml: add missing ./sx/sx:/app/sx bind mount for
sx_docs (root cause of "Unknown component: ~sx-layout-full")
- async_eval.py: add evaluation modes table to module docstring; log
error when async_eval_slot_to_sx can't find a component instead of
silently falling through to client-side serialization
- helpers.py: remove debug logging from render_to_sx_with_env

_aser_component expands component bodies in SX wire format mode,
but was evaluating kwarg values with async_eval (HTML mode). This
caused SxExpr kwargs to be fully rendered to HTML strings, which
then broke when serialized back to SX — producing bare symbols
like 'div' that the client couldn't resolve.
Fix: use _aser() for kwarg evaluation to keep values in SX format.

(filter (feTurbulence ...)) inside (svg ...) has no keyword first arg,
so the keyword-only check dispatched it as a HO function. Now also
check SVG/MathML context (ns in client, _svg_context in server).

Hyphenated names like app-url are variables, not custom elements.
Only treat as custom element when first arg is a Keyword (tag call pattern).

- Fix filter/map dispatching as HO functions when used as SVG/HTML tags
(peek at first arg — Keyword means tag call, not function call)
- Add html: prefix escape hatch to force any name to render as an element
- Support custom elements (hyphenated names) per Web Components spec
- SVG/MathML namespace auto-detection: client threads ns param through
render chain; server uses _svg_context ContextVar so unknown tags
inside (svg ...) or (math ...) render as elements without enumeration

Replace Tailwind class strings with native SX expressions:
(css :flex :gap-4 :hover:bg-sky-200) instead of :class "flex gap-4 ..."
- Add style_dict.py: 516 atoms, variants, breakpoints, keyframes, patterns
- Add style_resolver.py: memoized resolver with variant splitting
- Add StyleValue type to types.py (frozen dataclass with class_name, declarations, etc.)
- Add css and merge-styles primitives to primitives.py
- Add defstyle and defkeyframes special forms to evaluator.py and async_eval.py
- Integrate StyleValue into html.py and async_eval.py render paths
- Add register_generated_rule() to css_registry.py, fix media query selector
- Add style dict JSON delivery with localStorage caching to helpers.py
- Add client-side css primitive, resolver, and style injection to sx.js

Both evaluators now use thunk-based trampolining to eliminate stack
overflow on deep tail recursion (verified at 50K+ depth). Mirrors
the sync evaluator TCO added in 5069072.

Page helpers return SX source strings from render_to_sx(), but _aser's
serialize() was wrapping them in double quotes. In async_eval_slot_to_sx,
pass string results through directly since they're already SX source.

Defpages are now declared with absolute paths in .sx files and auto-mounted
directly on the Quart app, removing ~850 lines of blueprint mount_pages calls,
before_request hooks, and g.* wrapper boilerplate. A new page = one defpage
declaration, nothing else.
Infrastructure:
- async_eval awaits coroutine results from callable dispatch
- auto_mount_pages() mounts all registered defpages on the app
- g._defpage_ctx pattern passes helper data to layout context
Migrated: sx, account, orders, federation, cart, market, events, blog

execute_handler was using async_render() which renders all the way to
HTML. Fragment providers need to return sx source (s-expression strings)
that consuming apps parse and render client-side.
Added async_eval_to_sx() — a new execution mode that evaluates I/O
primitives and control flow but serializes component/tag calls as sx
source instead of rendering them to HTML. This mirrors how the old
Python handlers used sx_call() to build sx strings.
Also fixed: _ASER_FORMS checked after HTML_TAGS, causing "map" (which
is both an HTML tag and an sx special form) to be serialized as a tag
instead of evaluated. Moved _ASER_FORMS check before HTML_TAGS.
Also fixed: empty? primitive now handles non-len()-able types gracefully.

Return _RawHTML wrapper so pre-rendered HTML in let bindings isn't
escaped when used in render context.
