 *
 * Rules (per D11):
 * - Up to SNIPPET_CONTEXT_CHARS before and after, clipped to block boundaries.
 * - Total max length: SNIPPET_MAX_LENGTH.
 * - When matched text alone exceeds budget, snippet contains first SNIPPET_MAX_LENGTH
 *   characters with highlightRange = { start: 0, end: snippet.length }.
 * - Invariant: highlightRange.start >= 0 && highlightRange.end <= snippet.length.
