/*!
 * LinkedIn Feed Pro — front-end styles
 *
 * Architecture notes
 * ------------------
 * 1. Everything is namespaced under `.lfp`. No bare element selectors exist in
 *    this file, so the plugin cannot restyle a theme's body, buttons or links.
 * 2. All visual decisions come from custom properties set per-feed by
 *    Style_Engine, so one stylesheet serves any number of differently-styled
 *    feeds on a page.
 * 3. Fallback values on every `var()` mean the feed still renders correctly if
 *    a property is missing — which is exactly what the "Auto" colour preset
 *    relies on to inherit the host theme.
