/* =============================================================================
   tb-library.css — Corpus Build Library (the Build tab's Builds hub), the
   corpus study panel, provenance badges, the corpus context lane, and the
   shared SC2 glossary tooltips (migrated from the retired learn-guide.css).

   Class namespaces:
     .tb-hub-*     the Builds hub modal chrome (tabs, panes)
     .tb-lib-*     library rail / card grid
     .tbl-*        study panel (tb-build-info.js) — also rendered inside the
                   replay viewer's analyst guide panel
     .tb-prov-*    per-step provenance badges in the editor build list
     .tb-cl-*      corpus context lane markers
     .gloss        shared glossary tooltip (modules/shell/glossary.js)

   Responsive contract: 480 / 768 / 1024 only. The hub modal goes full-sheet
   under 768px; the library rail collapses to a horizontal scroll strip.
