Cascade (distinctive, not exhaustive):
- S389 Word Complexity / jargon-density bar (polysyllable %; ZH shows N/A).

- S392 Forward Citation Graph (outgoing internal links by category).
- S393 Sentiment/Tone Analyzer (bilingual bar; analytical/cautionary/urgent/reflective).
- S394 Related Articles by Topic Similarity (Jaccard on headings/keywords; top-3 chips).
- S395 Print-friendly export (print CSS hides chrome, inlines S385 footnotes, orphan/widow control).
- S396 QR Code for Sharing (floating modal; api.qrserver.com, no-referrer).
- S397 Social Share Buttons (X/LinkedIn/Facebook/Email/Copy; no tracking pixels).
- S398 Word Count / Reading Stats widget (6 stats; reading time at S390 speed).
- S399 Cognitive Load Calculator (0–100 index + tier bar; EN syllable heuristics / ZH char-density).
- S402 Inline TOC Progress Checklist (83 UX announced at ship; progress against on-page headings).
- S405 Footnote Reference Hover-Preview — replaces S385’s non-interactive tooltip with bilingual pin-able preview, clickable citation URL, ESC dismiss, viewport-flip, dark/print/reduced-motion. 120 files. Verified LIVE on absence-as-evidence.html + ai-wellbeing-framework-zh.html.
Why it matters for cold readers: the site has become a full reading environment (summarize, measure load, share, print, hear at your speed) without accounts or telemetry. Prior desk S388 = 71 UX; cascade lands at 84 UX features.
