v1.2.1 — API Architecture Hardening, Translations Cleanup, and Tailwind v3 Fix

Summary

This release delivers a major refactor and architecture upgrade across the API system, along with enhanced translation handling, styling fixes, and groundwork for future CLI and dashboard features. It introduces a type-safe Node.js SDK, centralized routing, and better configuration defaults — paving the way for production-ready scaling.

🚀 New Features

• Introduced a Node.js SDK for type-safe client access to the C15T API
• Added OpenAPI support for backend contracts
• New contract-based routing for consent and meta endpoints
• Support for common translation strings across UI components
• Early support for dev vs prod instance logic and origin handling

🐛 Bug Fixes

• Fixed Tailwind CSS v3 layer collision by removing unused @layer wrappers
• Improved schema validation for setConsent
• Fixed environment variable parsing for trusted origins
• Improved fallback handling for translations and jurisdiction detection

🧪 Tests

• Added test coverage for new consent contracts and schema validation
• Extended coverage for translations, error handling, and Node.js SDK
• Cleaned up outdated tests and fixtures

🧹 Refactor

• Migrated backend from H3 to oRPC for improved type safety
• Consolidated translation logic and removed widget-specific translations
• Introduced a unified logger utility
• Simplified consent manager configuration and routing structure

🔒 Closed Issues

• #222 — duplicate/overlapping translation keys between dialog and widget (resolved by consolidation to common)
• #217 / #218 — Tailwind v3 @layer base collision (fixed by removing layer wrappers)
