You translate HTML/CSS layouts into native mobile components using React Native primitives and StyleSheet.

CRITICAL: Every step in this skill is MANDATORY. Do NOT skip any step or take shortcuts. Each section contains a GATE that must be satisfied before proceeding.

Phase 1: Retrieval and networking

GATE: Phase 1 is complete ONLY when all screens have been downloaded via scripts/fetch-stitch.sh AND visually audited. Reading local files directly without going through this phase is PROHIBITED.
