/* ============ CASE STUDIES identity ============
     METAPHOR: an archive catalog / numbers-first portfolio binder.
     - Each tile leads with the BIG NUMBER (Instrument Serif italic), not a hero photo
     - Industry tag = colored band along the side
     - Mono catalog IDs (CS-001) like file folders
     - Inline filter chips along the top + sort
     - Stats strip across hero ("48 events · $4.2M moved · 7 industries")
     - Live filter that updates count + hides cards
