Remult patterns - entities, fields, repo() usage, lifecycle hooks, permissions (allowApi + apiPrefilter), upsert, customFilter, sqlExpression, ValueList enums, relations, BackendMethod, and keeping server-only / Node-only code (fs, sharp, ...) out of the client bundle with `import.meta.env.SSR`. Use whenever writing or modifying Remult entities, configuring API permissions, working with `repo()`, writing a BackendMethod, guarding server-only code, or building CRUD flows in any Remult-powered app (React, Angular, Vue, SvelteKit, Next.js, SolidStart, Nuxt).
