/**
 * Static-variable initialization safety net.
 *
 * Agency's `static const` declarations are compiled to module-level
 * `let` bindings whose assignment happens inside a per-module init
 * function (`__initializeStatic`). Until that function runs, the
 * binding holds an unset value. Historically it was plain `undefined`,
 * which meant a cross-module read before init silently produced
 * `undefined` and propagated through expressions like
 * `fooStatic = barStatic + "!"` as `"undefined!"`.
 *
 * To turn that silent failure into a loud one:
 *
 *   1. Codegen initializes every `static const` binding to
 *      `__UNINIT_STATIC` (a unique sentinel value).
 *   2. Codegen wraps every *read* of a static name with
 *      `__readStatic(value, name, moduleId)`.
 *   3. `__readStatic` returns the value unchanged if it's not the
 *      sentinel, or throws a clear error if it is.
 *
 * The wrapper is transparent — `__readStatic(x, ...)` evaluates to the
 * same value `x` would have, so binary operations, template
 * interpolations, indexing, and spreads all continue to work without
 * any change to user code or generated expression shapes.
 */
/**
 * Sentinel assigned to `static const` bindings before their initializer

 * symbols, frozen objects, etc.
 *
 * The codegen references this by name in the emitted source; do not
 * rename without updating the codegen.
