/* ==========================================================================
   TECH STACK TICKER  (#ticker) - page order 3
   Builds on the foundation .marquee / .marquee__track mechanism:
   - .marquee already provides overflow:hidden, edge mask, the `marquee`
     keyframe (translateX 0 -> -50%), pause-on-hover, and the reduced-motion
     kill switch. We only layer ticker-specific layout + item styling here.
   All rules scoped under #ticker so they never collide with other sections.
