- Root container uses calc(100vh - 220px) for fixed viewport height - All flex children use min-h-0 to enable proper overflow scrolling - Removed duplicate bottom nav buttons (Zurueck/Weiter) that appeared in the middle of the chunk text — navigation is only in the header now - Chunk text panel scrolls internally with fixed header - Added prominent article/section badges in header and panel header - Added chunk length quality indicator (warns on very short/long chunks) - Structural metadata keys (article, section, pages) sorted first - Sidebar shows regulation name instead of code for better readability - PDF viewer uses pages metadata from payload when available Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
