v1.3.0

Reader-only feature: the Constitution of Kenya now navigates itself. "Article N", "Chapter N", and list patterns like "Articles 152, 154, 155 and 156" become in-text buttons that jump to the referenced passage. When a reference names a specific sub-clause — "Article 142(2)" or "Article 136(2)(a)" — the destination flashes just that clause, not the whole article.

🔗 Clickable cross-references (#67)

• New renderProse() helper detects Article|Articles|Chapter|Chapters N(subpara)? patterns. Unknown article/chapter numbers stay as plain text so JSON typos never ship a dead link.
• Multi-number list parser: "Article 144 or 145" makes both numbers clickable; "Articles 152, 154, 155 and 156" makes all four. A continuation regex walks forward after the primary anchor eating ", N", " or N", " and N" separators.
• Self-references (an article mentioning its own number in its own summary) are no-ops.

↩️ Back-to-caller pill

• When the reader follows a reference, a "↵ Back to Article X" pill appears in the viewer header. Clicking it rewinds one hop — the history stack supports multi-hop chains (229 → 251 → 30 → back → back → back).
• Sidebar/keyboard/prev-next navigation clears the stack; the pill is specifically for "I followed a reference" flow.

💡 Clause-scoped arrival flash

• On ref click with a clause path, the matching (N) paragraph flashes a soft yellow (rgb(254, 249, 195)) and fades to transparent over ~2.4s.
• Plain "Article 144" refs produce no body flash — the page switch itself is the feedback.
• scrollIntoView({ block: 'nearest' }) so short articles (Art. 136, 2 paragraphs) don't push the outer page down; the clause is scrolled only when it's actually below the fold.

🛠 Fixes inside this release

• Whole-article flash (initial attempt) was too broad — scoped down to the cited clause.
• Header-vs-body flash mix-up — highlight now sits on the article text, not the chapter chip.
• Translucent amber was being washed out by a bg-white/70 parent — switched to solid yellow-100.
• tsc TS2802 on [...matchAll(...)] — replaced with exec-loop to avoid toggling downlevelIteration on the shared tsconfig.
