/**
 * Phase 6 widget appearance builders.
 *
 * Extracted from `pdf-renderer.ts` during M4 — this module owns
 * everything required to materialize PDF AcroForm widget appearance
 * streams (the `/AP /N` content), plus the "flattened" path that
 * inlines the same appearance into the page graphics for callers
 * that opt into `flattenForms`. The renderer still owns object
 * numbering (via `RenderContext`) and stitching widget objects into
 * the page tree; this module is pure command-stream construction.
