 * Plugin Name: Asterion — Align + style footer column sub-titles
 * /?av_fix_footer_headings=1
 *
 * Standardizes the 4 footer column headings (Solutions / Company / Legal /
 * Contact) with eyebrow-style typography : gold, uppercase, letter-spacing,
 * consistent size. Tightens the brand heading. Aligns columns to flex-start
 * so sub-titles sit at the same vertical baseline.
 *
 * Idempotent — re-runs are safe.
