/* ===========================================================
   MODULE: PARTNER SECTION
   File: partner-section.css

   RESPONSIBILITY
   - Full-width horizontal partner "band"
   - Cards with background images + text overlay
   - Auto-scrolling is handled in JS, but layout/hover/typography is here

   NEW / UPDATED:
   - Images live in /modules/partner-section/images/
   - .partner-card__bg--fallback is shown if no specific image AND no default.jpg
     -> big ÅreTaxi-red block so it's very obvious something's missing
   - Still responsive, still using CSS vars injected by PHP

   2025-10-31 UPDATE:
   - Subtle left/right nav buttons (.atx-partner-nav)
     - absolutely positioned inside viewport
     - default: semi-transparent dark
     - hover: ÅreTaxi red
     - chevrons are white
