   Production version of /lab/shared/lab.css (design review, PR #97).
   Four voices, each with one job:
     --g-sans    Inter (self-hosted, OFL)  display + interface
     --g-serif   Gambetta                  long-form reading
     --g-mono    system mono               12px labels only
     --g-song    Source Han Serif TC       classical Chinese
     --g-seal    seal-script subset        marks only (视 框 察, city seals)
   Import this file before a section stylesheet; it defines tokens and faces, no layout. */
