/**
 * Render a {@link FlowDoc} to a self-contained HTML document (ir-design §7).
 *
 * A flow medium: no pagination, no layout engine and no fonts to embed, so this
 * is a pure, zero-I/O transform. `flow.body` already carries FINAL effective
 * properties (the Stage-6 contract), so values map straight to CSS; every read
 * still routes through the cascade resolver over the empty sheet, a memoized
 * identity on reader output. Charts and shapes emit as inline SVG; deliberately
 * out of scope (reported as losses): inline math and headers/footers (no fixed
 * pages to band them onto). Page-break hints map to CSS `break-before`.
 *
 * @param flow The format-neutral interlayer document tree.
 * @returns The encoded HTML bytes plus the recorded {@link Loss} list.
