What's Changed

Added

• Section Visual Embedding -- DINOv2 ViT-B/14 section-level visual embedding (768D L2-normalized vectors) with PII protection and graceful degradation
• Section Screenshot Fallback -- Playwright-based individual section screenshots for out-of-range sections, with batch processing and type-aware duplicate detection (cosine > 0.995)
• Section Merge/Split Post-Processor -- 4 rules: same-type merge (3+), empty absorption, same-heading merge, oversized split (>10,000px)
• Blank Image Detection + Dynamic Fallback -- Detects lazy-loading unrendered sections and re-captures via Playwright
• Lazy Loading Scroll -- Pre-scrolls pages before screenshot to trigger IntersectionObserver-based lazy loading
• Multi-Tile Capture -- Splits large sections (>viewport height) into tiles for complete visual coverage (default 20 tiles, max 100)
• Type-aware dedup helper -- Extracted shouldSkipDuplicateVision() with 7 tests

Fixed

• onnxruntime-node ABI mismatch -- Pinned version to fix Node.js ABI crash
• isBlankImage dark theme false positive -- Dual-condition check (stddev + mean brightness)
• Pre-Return Pause race condition -- Fixed planned worker restart timing
• Dynamic Fallback 3 bug fixes -- isBlank logic inversion, buffer release, excludeIds for Rule 3
• undici 7.18.2→7.24.3 -- Resolved 6 vulnerabilities (3 high, 3 medium)
• flatted >=3.4.0 -- Resolved DoS vulnerability via pnpm override

Changed

• Fallback viewport unified to 1920x1080
