no-oversized-css-custom-property-values

Warn when CSS custom properties hide large shadow, filter, blur, or gradient values that can later be reused widely.

What this catches

• custom properties with too many expensive rendering functions
• shadow/filter/gradient token values with oversized comma-separated layer lists

Rule options

Option	Default	Why
maxFunctions	8	Allows richer design tokens but catches tokens hiding large rendering pipelines.
maxListItems	10	Allows normal layered tokens but catches very large shadow, filter, or gradient lists.
