Site audit: OG still on v0.8.0, offline claim, privacy diagram, a11y

[jatinkrmalik]

Scheduled 2026-09-01 audit of https://vocamac.com against PRODUCT.md and the brand book. Core ship truth is fine (VocaMac Beta v0.9.0, macOS 14+ Apple Silicon, AGPL-3.0, model download and update checks named). These five still need a pass.

Tasks

• Stale social preview. https://vocamac.com/og-image.png (og:image / twitter:image) still says v0.8.0 beta while the live page and release are Beta v0.9.0. Regenerate the OG image with v0.9.0.
• Unqualified offline claim. On https://vocamac.com/features/clipboard-preservation/ the comparison table says Works offline — Yes. That reads like a product-wide offline guarantee. The homepage already says model downloads and update checks use the network. Prefer something like On-device transcription after model download. Brand book §5.3.
• Privacy diagram understates engines. Homepage #privacy route step names only WhisperKit / CoreML, while the same page says v0.9.0 also ships Parakeet, Apple Speech, and ONNX. Label it Selected on-device engine and list the engines under that.
• Feature section accessible name is the whole article. Feature pages such as https://vocamac.com/features/apple-silicon-native/ use section[aria-labelledby="feature-content-title"] pointing at article#feature-content-title, which wraps the entire article. Move id="feature-content-title" to the first h2, or drop the aria-labelledby.
• Copy feedback is silent. In script.js, [data-copy] > .copy-btn flips Copy to Copied / Press ⌘C with no live region, so screen readers may miss the result. Add a polite status region or aria-live="polite".

No existing open website/audit duplicate turned up. Do not treat this as a shipping-status change.
