// Package premium declares the configuration template specs for premium
// (SHARED_POOL / LOGICAL_CLUSTER) clusters and wires them into a templategen
// Generator. Each spec's content (Base + Apply) lives in its own component file
// (premium_*.go) so it can be owned and edited by that component's dev in
// isolation.
//
// Convention (see templategen.Spec): Base holds the LATEST version's config;
// Apply adapts older / in-test versions down from it. When a new version becomes
// the latest, move its config into Base and add an Apply branch for the version
// it replaced — never grow Base with a stack of "new version adds X" branches.

// their own version lines, add cases here — this is the single place that owns
// the premium per-component version policy.
