- Simplified and cleaned guards: removed redundant checks, unified coordinate comparisons in IntersectionObserver, simplified hash extraction.
- Robustness improvements: added viewport fallback for rootBounds=null, replaced silent guards with console.assert and moved checks to call sites.
- Efficient re-scan: introduced anchorsCount/anchorsSig to detect TOC mutations and skip unnecessary re-observe, while keeping mapping valid after resetState().
- Removed legacy code: dropped unused contentFrameTop metric and clarified inline comments.
- Hash remapping: implemented resolveMovedFragment() to transparently remap outdated hashes when TOC entries are reordered and renumbered.
…valid - Introduced anchorsCount/anchorsSig to detect changes and avoid redundant re-observe. - Rebuild anchor→data mapping after resetState() even if set unchanged. - Guarded handleIntersect against missing mapping during TOC mutations.
