/**
 * Static tree rendering — box-drawing hierarchy with depth, fold, and icons.
 *
 * @remarks
 * Part of the Human Render Contract (Epic T10114, ADR-077). Consumes a
 * {@link TreeResponse} (flat, pre-order list of {@link FlatTreeNode}s) and
 * emits a box-drawing tree that mirrors the canonical Saga → Epic → Task →
 * Subtask layout.
 *
 * Connector glyphs:
 * - `├─` non-last child
 * - `└─` last child
 * - `│ ` vertical continuation across a non-last ancestor
 * - `   ` last-sibling ancestor (no vertical bar)
 *
 * Each rendered row carries the matching {@link KindIcon} prefix and a
 * trailing {@link StatusIcon}. When the {@link AnimateContext} indicates
 * `noColor` mode (or `opts.asciiBoxDrawing === true`) glyphs collapse to
 * ASCII fallbacks (`+-`, `| `, `   `) and icons resolve via {@link ascii}.
 *
 * @epic T10114
 * @task T10128
 * @subtask T10142
