What we check

Every image needs an alt attribute for screen readers (WCAG 1.1.1)
📝

Inputs must have associated labels so users know what to type
🗂️
Heading Structure
H1→H2→H3 hierarchy — screen readers navigate by headings
🔗

No "click here" — links need descriptive text out of context
🌍
Language Declaration
The <html lang="..."> attribute tells screen readers the language
🔍
ARIA Landmarks
<main>, <nav> landmarks let users jump directly to key sections
