- repertoire-index.php: add $colHasMatches per-column guard.
Entries in a column are only faded when that column has at least one
matched entry in the current result set. When a dimension has no
matched entries (e.g. no thesis has orientation_id set yet), the
entire column stays fully interactive — all values remain clickable.
This fixes: empty columns, forced single-select, cascade fading.
- Database.php: revert allAp/allOr/allFi to full lookup-table queries
so all known values are always shown (not just ones linked to theses).
- common.css: body is now a flex column; main gets flex:1 + min-height:0;
header-search-wrap gets flex-shrink:0; duplicate html/body blocks merged.
- public.css: removed redundant top-level main block; home-main gets min-height:0.
- repertoire.css: search-main gets min-height:0 for proper flex scroll.
