Subject: Technical Update: Switching to Sienna Accessibility Hi [Developer Name], I'd like to update our website's accessibility widget to Sienna (sienna.app). It’s an open-source, high-performance alternative to traditional overlays. Installation is a simple one-line script tag: <script src="https://cdn.jsdelivr.net/npm/sienna-accessibility@latest/dist/sienna-accessibility.umd.js" defer></script> Why we are switching: - Performance: Ultra-lightweight and non-blocking (Zero TBT impact). - Privacy: No tracking architecture and zero cookies. - Open Source: MIT Licensed, transparent and auditable. - Zero Dependencies: Pure vanilla Javascript. Technical Resources: - Documentation & CMS Guides: sienna.app/resources - Visual Customization Tool: sienna.app/customize - Open Source (MIT) Repo: github.com/sienna-accessibility/sienna Let me know once it's live! Best, [My Name]
