Subject: [PATCH 1/7] redesign(documents): document-first viewer with sticky
 evidence rail

- Desktop: widen evidence rail 420->480px, make it sticky with internal
  scroll; widen page container to 1440px and centre the document column;
  hero info cards flow 3-up.
- Tablet (md): deliberate layout instead of the phone stack - full-width
  PDF, evidence + indexed text 2-up, details/summary 2-up.
- Phone: document-first order (anchors, PDF, evidence, collapsible text).
- Remove the Index health block and duplicated actions (preview-toolbar
  Open/Download, per-chunk Open source); keep the Canvas/Browser toggle
  as a single quiet control.
- Fix latent shell bug: overflow-x-hidden on #main-content made it the
  sticky scrollport while the window scrolls, disabling every sticky
  descendant on sm+; use overflow-x-clip there instead.
- Update ui-smoke ordering assertions for the document-first phone flow.

Subject: [PATCH 2/7] fix(documents): scope deep-link scroll to the visible
 indexed panel

Both IndexedTextPanel copies render the pinned chunk, so the scroll-to-pin
querySelector returned the first (hidden) match: display:none on lg+ and a
collapsed <details> on phones. Skip display:none matches, ignore chunks inside
a closed <details>, and expand the mobile section when the pinned chunk only
exists there, so ?page=&chunk= deep links land on the copy the user can see.

Addresses CodeRabbit review on #489.
