/*
Filename:      sponsor.css
Created by:    Kris Korsmo
Organization:  Leading Edge Digital Media - www.leadingedge.net
Purpose:       Sponsor slots rendered by api/sponsorshipDisplay.cfc
Last Updated:  10/20/2026

Loaded by common/template.cfm and by the standalone entity templates
(index-rally, index-event, index-article, index-car), so it cannot rely on
style.css or eg-premium.css being present - colours are spelled out with the
eg-premium accent as a fallback.

A slot is <aside class="eg-sp eg-sp--{format} eg-sp--{tier} [eg-sp--{variant}]">.
Formats: banner (4:1, full width), tile (6:5, grid), logo (2:1, strip).
Every slot carries a visible "Sponsored" label (FTC disclosure) - do not hide it.
