/* ---------------------------------------------------------------
   Browse view — filter drawer + active-chip strip
   Rules:
   - Each filter row is ONE LINE: [label][controls...].  Labels never
     stack above controls except in the single "Century of birth" row.
   - Chip groups never break: chips inside a group stay together on a
     single line.  Drawer column width is sized to make that fit.
   - Section titles are LEFT-aligned at the section's left edge.
