Resolve TypeScript and ESLint errors in a Vue 3 frontend by enforcing declaration-site type definitions, mirroring backend Rust structs as TypeScript interfaces, and systematically removing unused code.

Avoid the any type during TypeScript refactoring by enforcing type safety conventions, defining declaration-site types, and tracing untyped API calls to their corresponding backend Rust structs.

Enforce Vue 3 linting rules for component naming and prop mutation by applying specific linting playbooks that restrict prop mutation, standardize component naming, and regulate template-scoped variable usage.

Increase ESLint strictness from warning to error without breaking CI by implementing a ratcheting rollout strategy that systematically enforces linting rules across the codebase.

Mirroring backend Rust structs as TypeScript interfaces is required for strict type checking to resolve untyped API calls and maintain type safety consistency across the web service layer.
