/**
 * Server-side syntax highlighting (MAIN-SCOPE §3 Highlight package). Produces a stable, serializable
 * token stream consumed by file previews (features/file-explorer-transfer.md) and git diff rendering
 * (features/git-checkout.md). Pure-JS / dependency-free regex tokenizer with graceful plain-text
 * fallback. Concatenating `tokens[].value` in order exactly reproduces the source (lossless).
 *
 * TODO(verify): the original package's exact highlighter library / grammar set.
