/*
 * Chiggle Academy — share bar.
 *
 * Companion to the OpenGraph + Twitter Card meta in inc/hooks-seo.php
 * (which handles link-preview unfurl when URLs are pasted into
 * WhatsApp / X / Facebook / Slack / LinkedIn). This adds the explicit
 * per-network buttons + a Web Share API trigger on supported browsers.
 *
 * Brand-consistent with the v0.11.52 sign-in modal aesthetic — navy +
 * gold palette, --radius-md corners, navy-at-low-alpha shadows. Two
 * tones:
 *   - light (default): on white/offwhite backgrounds (preview, certificate)
 *   - dark:            on navy backgrounds (homepage CTA section)
 *
 * Renderer: inc/hooks-share.php → chiggle_render_share_bar().
