Short summary

Developer shared architectural patterns from building Laravel backends for Flutter mobile apps and refreshing a Next.js marketing site, all completed the same day. Three connected lessons: API Resources must be treated as permanent contracts—every field you expose to mobile apps becomes an unchangeable obligation; pricing pages need a single source of truth (one plans.ts file); and payment systems need reconciliation layers as safety nets for failed webhooks. Core principle: drift appears whenever architectural truth is scattered across multiple locations.
