Replace generic orange "D" placeholders with the duck mascot logo
in all branding touchpoints: navbar header, home page hero, studio
import view, and browser favicon.
Add document and clock icons above the stat numbers for better visual
context. Accent border and icon color on hover for consistent
interactive feedback across the app.
Add contextual icons (gear, checkmark, grid) to Configure, Verify,
and Prepare tabs. Replace flat white/shadow active state with accent
color background for clearer visual feedback. Use inner padding and
individual border-radius for a modern segmented control look.
Extract bounding boxes from chunk doc_items provenance in the chunker,
propagate through domain/service/API layers, and render highlighted
bboxes on canvas when hovering a chunk card. Reset highlights on
mode and page changes to prevent stale visual state.
Filter chunks by current PDF page for consistency with Verify mode.
Add collapsible chunking config section and paginated chunk list.
Show BboxOverlay in Prepare mode so users see element bounding boxes.
Fix scroll containment on prepare panel.
