Divide-between-children macro (.sf-divide)

[jackgranatowski]

Problem

.sf-divider is a standalone separator element, but there's no one-shot way to place rules between all direct children of a container (a very common list/stack pattern). Today you add borders manually.

Scope

• .sf-divide applying > * + * { border-block-start: var(--sf-border) } (plus a --vertical variant using border-inline-start), reusing divider tokens.

Acceptance

• .sf-divide (+ vertical) emitted; documented
