   Flavor Affiliate — Centralized z-index Token System (#92)

   All z-index values used across the plugin are defined here as CSS
   custom properties. Components reference these tokens instead of
   hard-coding z-index values, eliminating stacking-context conflicts.

   Scale:
     base      1   — default card / element lift
     sticky   10   — sticky table columns
     header  100   — site header (SWELL)
     overlay 1000  — modals / popups
   ========================================================================== */

:root {
    /* Base elements */
    --flv-z-base: 1;

    /* Sticky table columns (compare table label) */
    --flv-z-sticky: 10;

    /* Site header (SWELL .l-header in critical CSS) */
    --flv-z-header: 100;

    /* Exit-intent popup overlay */
    --flv-z-overlay: 999999;
