Zoom is locked
The viewport meta contains user-scalable=no or a maximum-scale close to 1.

This is what you should do: Remove user-scalable=no and maximum-scale: <meta name="viewport" content="width=device-width, initial-scale=1">.
5 CSS rulen with possibly too low text contrast
Required: 4.5:1 (normal) or 3:1 (large text). With an “assumed page background” the actual background could not be determined reliably — check in the browser if in doubt. Found among others: `.text-\[rgb\(250\`: #fafafa auf #fafafa (Vorfahren-Hintergrund) = 1.00:1 · `.text-\[\#a0a0a0\]`: #a0a0a0 auf #ffffff (Standard) (Seitenhintergrund, angenommen) = 2.61:1 · `.text-\[\#33b279\]`: #33b279 auf #ffffff (Standard) (Seitenhintergrund, angenommen) = 2.70:1 · `.text-\[rgb\(29\`: #1d9bf0 auf #ffffff (Standard) (Seitenhintergrund, angenommen) = 3.00:1 · `.ghfe_a_dialog .ghfe_a_dialogcta`: #718900 auf #ffffff (Standard) (Seitenhintergrund, angenommen) = 3.98:1
.text-\[rgb\(250\, .text-\[\#a0a0a0\], .text-\[\#33b279\], .text-\[rgb\(29\, .ghfe_a_dialog .ghfe_a_dialogcta
This is what you should do: Darken the text colour or lighten the background until the relevant minimum value is reached. Never use colour as the only distinguishing feature.
Already handled correctly
- Text alternatives: no automatically recognisable issues
- A <main> landmark exists

Method & limits
On 9/3/2026 the HTML that vercel.com delivers on a first visit without login was checked, plus up to four linked CSS files from the same domain. Checked: colour contrast (from CSS), text alternatives, form labelling, names of controls, heading structure, page title and page language, zoom lock, duplicate ids, positive tabindex values, landmarks.
Not checked: anything that arises via JavaScript, keyboard operability, visible focus, focus order, screen-reader announcement, content behind login, subpages. The automated test finds roughly 20–35% of WCAG breaches — the rest needs a manual check. A snapshot, not a legal decision.
