/**
 * SyncTeX — bidirectional source↔PDF lookup.
 *
 * Forward: (sourceFile, line) → list of PDF rectangles.
 * Reverse: (page, x, y) → list of source locations.
 *
 * Implementation note: the .synctex.gz format is a small text format that
 * SyncTeX's reference parser is ~2KB of code. For v1 we ship a JS-only
 * implementation. If perf turns out to be a problem we'll cross-compile the C
 * `synctex` parser to its own `synctex.wasm` and swap it in transparently.
