/* Small Bids — playful, pattern-heavy case study.
   Theme: cream surface, pink nav, red accent, emerald + deep teal panels.
   Layout notes:
   - Page is very tall (16867px in Figma). We use flood panels + a hscroll
     deck gallery + alternating tilts for visual rhythm.
   - A fixed section counter lives top-right (see .sb-counter), updated by
     small-bids.js as you scroll.
