// Circle Suite — Team Grants (Vertex L7, Corona L8).
//
// The problem this fixes: every tool from L1 to L8 was a "me" tool — help ME
// write, help ME post, help ME measure. But past the first couple of levels the
// business is not about you. It is get two, help your two, teach them to teach.
// So the top of the ladder was scaling the wrong axis: more of your own
// capability, at double the price each rung.
//
// A grant lets a leader hand Suite capacity DOWN into their own organisation —
// impressions, generations, page builds, ad batches. Three things make it work:
//
//  1. It comes from a POOL that is a perk of the level, not a tax on the
//     leader's own allowance. Making leaders choose between equipping their
//     team and using their own tools would just mean nobody grants anything.
//  2. It can only go to someone inside the grantor's own organisation, checked
//     against the contract. This is not a way to hand capacity to strangers.
//  3. It expires with the month, like every other allowance here. Grants are
//     for unblocking someone now, not for building up a balance.
