collect-then-substitute resolver can't handle data dependencies between
I/O results and control flow, so handlers need inline async evaluation.
Evaluation modes
~~~~~~~~~~~~~~~~
The same component AST can be evaluated in different modes depending on
where the rendering boundary is drawn (server vs client). Five modes
exist across the codebase:
Function Expands components? Output Used for
-------------------- ------------------- -------------- ----------------------------
_eval (sync) Yes Python values register_components, Jinja sx()
_arender (async) Yes HTML render_to_html
_aser (async) No — serializes SX wire format render_to_sx
_aser_component Yes, one level SX wire format render_to_sx_with_env (layouts)
sx.js renderDOM Yes DOM nodes Client-side
_aser deliberately does NOT expand ~component calls — it serializes them
as SX wire format so the client can render them. But layout components
(used by render_to_sx_with_env) need server-side expansion because they
depend on Python context (auth state, fragments, etc.). That's what
_aser_component / async_eval_slot_to_sx provides: expand the top-level
component body server-side, then serialize its children for the client.

Named layout presets for defpage.
Each layout generates header rows for full-page and OOB rendering.

Built-in layouts delegate to .sx defcomps via ``register_sx_layout``.

atom in ``(css :flex :gap-4 :p-2)``), and each value is the CSS declaration(s)
that class produces. Declarations are self-contained — no ``--tw-*`` custom

Generated from the codebase's tw.css via ``css_registry.py`` then simplified
to remove Tailwind v3 variable indirection.

"""
Style resolver — ``(css :flex :gap-4 :hover:bg-sky-200)`` → StyleValue.
Resolves a tuple of atom strings into a ``StyleValue`` with:
- A content-addressed class name (``sx-{hash[:6]}``)
- Base CSS declarations
- Pseudo-class rules (hover, focus, etc.)
- Media-query rules (responsive breakpoints)
- Referenced @keyframes definitions
Resolution order per atom:
1. Dictionary lookup in ``STYLE_ATOMS``
2. Arbitrary value pattern match (``w-[347px]`` → ``width:347px``)
3. Ignored (unknown atoms are silently skipped)
Results are memoized by input tuple for zero-cost repeat calls.
