Walkthrough

Adds a position option for Select content (popper default, item-aligned), documents the option with examples and notes, and updates contributor guidance/agent rules about a Soon badge. Runtime: resolves position from props → appConfig → default, exposes position to content props, derives isItemAligned, replaces inline value/placeholder markup with RSelectValue, conditionally uses SelectViewport for item-aligned viewports, and adjusts viewportRef exposure to return the underlying element. Theme: moves animation classes into a variants.position config. Playground: example using content.position: 'item-aligned'.
