// Display order for the agentic-backend picker. Replaces the previous
// category-grouped layout — partners explicitly asked us to drop the
// "MOST POPULAR / AGENT FRAMEWORKS / ENTERPRISE / EMERGING" buckets,
// which read as a tier list and worked against the partnership story.
// Both the sidebar dropdown and the docs-landing "Switch backend" grid
// render a single flat list in this order.
//
// Built-in Agent (CopilotKit) is intentionally NOT in this list: the
// sidebar variant pins it at the top as a separate row, and the docs
// landing already renders the page in BIA's "Continue with…" frame.
