Build a sponsors footer with Tailwind CSS: supporter logos arranged in tiers — platinum (large, two or three per row), gold (medium, four per row), and community (small, many per row) — with tier labels on the left of each row. Grayscale the logos until hover, keep each tier's logos uniform in size, and put the small print below the last tier with a 'become a sponsor' link.
