Tailwind CSS Gradients

v4 expanded the gradient API from v3's eight linear directions to a full three-family system (linear, radial, conic) with seven interpolation colour spaces, angle-based linear gradients, and percentage stop positions. v3 stays linear-only with the legacy bg-gradient-* prefix.

Companion skills :

• tailwind-syntax-utility-classes : the broader background utility surface
• tailwind-core-v3-vs-v4 : the v4-renamed utilities table (bg-gradient -> bg-linear)
• tailwind-impl-migration-v3-v4 : codemod that handles the rename
