* ═══════════════════════════════════════════════════════════════════
*
* Centralized z-index scale to prevent conflicts and ensure proper
* stacking context across all components.
*
* SCALE ORGANIZATION:
*
* Base Layer (0-99)
* 0 - Default document flow
* 1 - Base stacking (content, cards)
* 10 - Raised elements (dropdowns within sections)
*
* Interface Layer (100-999)
* 100 - Dropdowns, tooltips
* 200 - Sticky headers, floating elements
* 999 - Overlays, backdrops
*
* Navigation Layer (1000-1099)
* 1000 - Main header (fixed navigation)
* 1005 - Mobile navigation menu
* 1010 - Hamburger icon
*
* Modal Layer (9000+)
* 9999 - Modals, alerts, critical overlays
*
* USAGE:
* Always use CSS variables (--z-*) instead of raw numbers
* Document any deviations in component comments
* Test stacking in both light and dark themes
*
* CURRENT ASSIGNMENTS:
* - Parallax background: -1 (fixed, non-variable)
* - Content sections: var(--z-base)
* - Header/Footer: var(--z-sticky) when sticky

* PERFORMANCE NOTES:
* - Only animate transform and opacity (GPU-accelerated)

* - Avoid animating layout properties (width, height, margin, padding)
