What problem does it solve? Building the Peajes (toll) module frontend requires following strict repo conventions—standalone Angular 19 components, custom CSS/SCSS, Font Awesome, typed contracts from agent 00—while staying inside a narrow ownership scope. This Skill guides the agent to implement the Excel upload wizard and catalog tables without violating module boundaries or introducing a foreign design system. ## Core Features & Use Cases - Excel Upload Wizard: Implements the multi-step wizard (upload .xlsx, 10-row preview, column mapping, invoice, validation) under src/app/components/peajes/wizard/. - Catalog Tables: Builds CRUD-style tables for peajes, estaciones, patentes, and pases under catalogos/ following the repo's card/button/loading-state UI pattern. - Contract-First Development: Consumes typed interfaces from agent 00's models and uses typed mocks until agent 01 delivers real Supabase services. - Use Case: Implement feature F02-03 (column mapping step) by importing PasadaColumnKey from the models folder, rendering the mapping UI with existing .btn styles, and verifying with ng test. ## Quick Start Implement the F02 wizard step for Excel preview in the Peajes module using the existing standalone Angular component pattern and typed mocks from the agent 00 contracts.
