/*
 * Free scheduling tools (round robin generator, league schedule maker) on the arena landing pages.
 * Scoped to .st-tool; uses the arena tokens (--lime, --purple, --f-ui, --f-display) with fallbacks.
 * Charcoal surfaces only (no navy). Inputs and buttons are at least 44px tall. The schedule table
 * scrolls inside its own container, so the page never scrolls sideways (checked at 320/390/1280).
