+/* PricingGrid.test.tsx — pricing copy regression guards.
+ *
+ * BIZ-3 (2026-05-29): the dashboard in-app pricing tile shipped with copy
+ * inherited from a retired "deployment_size" field on /deploy/new:
+ *   - Hobby tile: "1 small deployment"
+ *   - Pro tile:   "50 GB object storage · 10 medium deployments"
+ *
+ * The backend handler (api/internal/handlers/deploy.go) has no
+ * deployment_size field — there are no small/medium/large pod sizes.
+ * Numbers come from plans.yaml deployments_apps. Marketing PricingPage
+ * (src/pages/PricingPage.tsx) dropped the size adjectives in the
+ * 2026-05-20 DOC-REALITY-DELTA sweep; the dashboard surface lagged.
+ *
+ * This test pins both strings out of the in-app pricing surface so any
+ * future copy edit that re-introduces them fails CI before it ships.
