- Server sends sexp source text, client (sexp.js) renders everything
- SexpExpr marker class for nested sexp composition in serialize()
- sexp_page() HTML shell with data-mount="body" for full page loads
- sexp_response() returns text/sexp for OOB/partial responses
- ~app-body layout component replaces ~app-layout (no raw!)
- ~rich-text is the only component using raw! (for CMS HTML content)
- Fragment endpoints return text/sexp, auto-wrapped in SexpExpr
- All _*_html() helpers converted to _*_sexp() returning sexp source
- Head auto-hoist: sexp.js moves meta/title/link/script[ld+json]
from rendered body to document.head automatically
- Unknown components render warning box instead of crashing page
- Component kwargs preserve AST for lazy rendering (fixes <> in kwargs)
- Fix unterminated paren in events/sexp/tickets.sexpr

- Load sexp.js in ~app-layout before body.js
- Auto-process <script type="text/sexp"> tags on DOMContentLoaded
- Re-process after htmx:afterSwap for dynamic content
- Sexp.mount(target, expr, env) for rendering into DOM elements
- Sexp.processScripts() picks up data-components and data-mount tags
- client_components_tag() Python helper serializes Component objects
back to sexp source for client-side consumption
- 37 parity tests all passing

Vanilla JS (no build tools) counterpart to shared/sexp/ Python modules.
Parses s-expression text, evaluates special forms, and renders to DOM
nodes or HTML strings. Full component system with defcomp/~name.
Includes:
- Parser: tokenizer + parse/parseAll matching Python parser exactly
- Evaluator: all special forms (if, when, cond, let, and, or, lambda,
defcomp, define, ->, set!), higher-order forms (map, filter, reduce)
- DOM renderer: createElement for HTML tags, SVG namespace support,
component invocation, raw! for pre-rendered HTML, <> fragments
- 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.
