/**
 * Comment marker that marks a function as an inline component (render prop),
 * e.g. `<Comp Title={({ msg: $msg }) => ...} />`.
 *
 * The JSX transform plugin (j20's jsx-transform) attaches this comment to the
 * function node *before* signal-compiler runs, so signal-compiler itself stays
 * JSX-agnostic — it only has to recognize the marker. This requires the JSX
 * transform to run first in the pipeline (separate Babel pass), because the
 * marker must already exist when signal-compiler's function visitor fires.
 *
 * Attach it with a block comment (NOT a line comment — `return // @marker`
 * would break under ASI):
 *
 * ```js
 * path.addComment("leading", " @signal-component "); // on the function node
 * ```
