/* =====================================================================
 * NGS Product Tabs — [ngs_product_tabs]
 *
 * Three style variants, switched via `data-style` on the root element:
 *   showcase  — info-rich stat-card tabs (default). Two-line content
 *               with an icon chip, title, and auto-counted item subtitle.
 *               Animated sliding indicator on the bottom.
 *   pills     — single-line pill buttons in a unified container, with
 *               a small count badge to the right of each label.
 *   compact   — slim flat pill buttons, single line, no counts, no
 *               container — for tight layouts.
 *
 * Each tab carries `--ngs-pt-accent-local` (set inline by JS from the
 * section's `data-icon` key) so the active state can color itself per-
 * section without us hard-coding a giant lookup table here.
 * ===================================================================== */
