/**
 * Border style handler with multi-group support.
 *
 * Single group (backward compatible):
 * - `border="1bw solid #red"` - all sides
 * - `border="1bw solid #red top left"` - only top and left
 *
 * Multi-group (new):
 * - `border="1bw #red, 2bw #blue top"` - all sides red 1bw, then top overridden to blue 2bw
 * - `border="1bw, dashed top bottom, #purple left right"` - base 1bw, dashed on top/bottom, purple on left/right
 *
 * Later groups override earlier groups for conflicting directions.
