/**
 * Element Trending Posts — frontend styles.
 *
 * Translated from the EGFR-Revamp Figma frames:
 *   featured post     615:610 (desktop 818, tablet 550, mobile 375)
 *   trending post     230:29
 *   trending speakers 236:145
 *   trending tags     230:84
 *
 * Every value that a designer might want to move lives in a custom property on
 * .etp-trending, so the global custom-CSS field in Settings can retheme the
 * output by overriding tokens rather than fighting selectors.
