# Consent wall blocks content — dev spec
Site: yahoo.com · Priority 1 · Urgent · Effort: Medium (2-5 days)

## Problem
The homepage is gated behind a privacy consent wall that must be dismissed before any content is visible, creating an immediate barrier to engagement.

## Evidence (from the live site)
> SEO title is 'Ihre Datenschutzeinstellungen' (German for 'Your Privacy Settings'), indicating a consent interstitial; body sample shows no main content until after the consent wall is dismissed.

## Current state
h1: No H1 present; cta: Sign in, See more stories on Yahoo 100, See forecast; notes: Consent wall blocks all content; user must interact before seeing any news or links.

## Required change
h1: Yahoo - News, Sports, Finance, and More; cta: Sign in, See more stories on Yahoo 100, See forecast; notes: Implement a non-intrusive consent banner that allows immediate access to content, with clear 'Accept' and 'Manage' options.

## Acceptance criteria
