Enriched the 4 articles in data.js with id, doctorId, hero color,
emoji, date, lede, and structured body blocks (paragraphs, headings,
bullet lists, tone-variant callouts).
New screens:
- ArticlesScreen — tag-filtered list with hero-card layout
- ArticleDetailScreen — hero block, meta row, lede, body renderer
(p/h/ul/callout), author card linking to doctor profile, CTA to
book the author, and "Related" footer
Home card and feed sections now link to detail and list screens.
