sx-headers attributes now use native SX dict format {:key val} instead of
JSON strings. Eliminates manual JSON string construction in both .sx files
and Python callers.
- sx.js: parse sx-headers/sx-vals as SX dict ({: prefix) with JSON fallback,
add _serializeDict for dict→attribute serialization, fix verbInfo scope in
_doFetch error handler
- html.py: serialize dict attribute values via SX serialize() not str()
- All .sx files: {:X-CSRFToken csrf} replaces (str "{\"X-CSRFToken\": ...}")
- All Python callers: {"X-CSRFToken": csrf} dict replaces f-string JSON
- Blog like: extract ~blog-like-toggle, fix POST returning wrong component,
fix emoji escapes in .sx (parser has no \U support), fix card :hx-headers
keyword mismatch, wrap sx_content in SxExpr for evaluation

When an HTML tag like (div) appears as a kwarg value in SX wire format,
callComponent evaluates it with sxEval (data mode) which doesn't handle
HTML tags. Now sxEval delegates to renderDOM for any render expression
(HTML tags, SVG tags, fragments, raw!, components).

_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.

Hyphenated names like app-url are variables, not custom elements.

- 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

- sx-editor.js: htmlToSx() via DOMParser, serializeInline for captions,
_childrenSx for ~kg-html/~kg-md, new kg-md edit UI

Both Python and JS parsers used next_token() which returns plain strings
for both delimiter characters and string values, making them
indistinguishable. A string whose value is ")" or "(" would be
misinterpreted as a structural delimiter, causing parse errors.
Fix: use peek() (raw character) for all structural decisions in
parseExpr before consuming via next_token(). Also add enhanced error
logging to sx.js mount/loadComponents for easier future debugging.

When server omits component source (cache hit), the script tag has
empty textContent. The early `if (!text.trim()) continue` was
skipping the data-components handler entirely, so components never
loaded from localStorage.

Server computes SHA-256 hash of all component source at startup.
Client signals its cached hash via cookie (sx-comp-hash). On full
page load: cookie match → server sends empty script tag with just
the hash; mismatch → sends full source. Client loads from
localStorage on hit, parses inline + caches on miss.

Three issues with the eager kwarg evaluation in renderComponentDOM and
renderStrComponent:
1. Data arrays (e.g. tags list of dicts) were being passed to sxEval
which tried to call a dict as a function — causing blank pages.
Fix: only evaluate arrays with a Symbol head (actual expressions);
pass data arrays through as-is.
2. Expression arrays like (get t "src") inside map lambdas lost their
scope when deferred — causing "get,t,src" URLs. Fix: eagerly evaluate
these Symbol-headed expressions in the caller's env.
3. Bare symbol `t` used as boolean in editor.sx threw "Undefined symbol".
Fix: use `true` literal instead.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
renderComponentDOM now eagerly renders kwarg values that are render
expressions (HTML tags, <>, ~components) into DOM nodes. But renderDOM
treated any non-array object as a dict and returned an empty fragment,
silently discarding pre-rendered content. Add a nodeType check to pass
DOM nodes through unchanged.

The string renderer's component call had the same deferred-evaluation
bug — and this is the path actually used for blog card rendering via
renderToString. Apply the same _isRenderExpr check to route render-only
forms through renderStr while data expressions go through sxEval.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The previous fix eagerly evaluated all kwarg expressions via sxEval,
which broke render-only forms (<>, raw!, HTML tags, ~components) that
only exist in the render pipeline. Now detect render expressions by
checking if the head symbol is an HTML/SVG tag, <>, raw!, or ~component,
and route those through renderDOM while data expressions still go
through sxEval for correct scope resolution.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
renderComponentDOM was deferring evaluation of complex expressions
(arrays) passed as component kwargs, storing raw AST instead. When the
component body later used these values as attributes, the caller's env
(with lambda params like t, a) was no longer available, producing
stringified arrays like "get,t,src" as attribute values — which browsers
interpreted as relative URLs.
Evaluate all non-literal kwarg values eagerly in the caller's env,
matching the behavior of callComponent and the Python-side renderer.

- String renderer: matches Python html.render output for SSR parity
- ~50 built-in primitives (arithmetic, string, collection, predicates)
- 35 parity tests verifying JS output matches Python output via Node.js
Also fixes Python raw! handler to properly unwrap _RawHTML objects.
