/**
 * Sapp Sponsors — front-end banner styles.

 * Goals:
 *  - Centered, full-bleed-within-max-width banner at every breakpoint.
 *  - No layout shift: images maintain natural aspect ratio.
 *  - Sensible vertical breathing room.
 *  - Max display width per slot (leaderboard 970 px, others fluid).
