accessibility-perceivable

Use this skill when the question is whether users can *perceive* the content — see it, hear it, or feel it — regardless of impairment. Trigger when designing color systems, picking text sizes, building image-heavy surfaces, working with video/audio, designing for low-vision users, or running an accessibility audit. Covers WCAG Principle 1 (Perceivable). Sub-aspect of `accessibility`; read that first if you haven't already.

# Accessibility — Perceivable

WCAG Principle 1: information and user-interface components must be presentable to users in ways they can perceive.

The four sub-criteria, simplified:

1. **Text alternatives** for non-text content.
2. **Time-based media** (audio/video) has alternatives.
3. **Adaptable** content can be presented in different ways without losing structure.
4. **Distinguishable** — color contrast, audio control, text resizing.

This skill covers each in practical detail.
