   Design notes
   - Every logo sits on a fixed square white plate, so any logo stays legible
     in both light and dark themes and all plates line up.
   - Logos are never cropped or upscaled: object-fit: contain with max-width /
     max-height only, so each logo keeps its natural proportions.
   - The company name is a visible caption next to the plate.
   - Missing logo files are hidden by script.js (the tile and, if empty, the
     whole strip), so a company without a logo simply shows nothing yet.
