+## Context
+
+The Agentic Semantic Web (ASW) is a CSS and HTML framework purpose-built for agent-authored web content. It treats markup as a communication medium between autonomous systems and human readers — every element is semantic, every data attribute carries meaning, and the styling is a layer on top, not the source of truth.
+
+ASW is a three-layer stack:
+
+1. **Pico CSS** — minimal residual styles as the base layer. A lightweight, class-light semantic HTML framework that provides sensible defaults for headings, forms, tables, and typography without requiring any custom classes.
+2. **Theme tokens** — CSS custom properties that define the visual identity. Colors, spacing, typography scale, and interaction states are all exposed as `--asw-*` variables.
+3. **Data-attribute extensions** — Custom properties and attribute selectors that extend the base framework with agent-oriented patterns: `[data-asw-type]`, `[data-asw-status]`, `[data-asw-agent]` for annotating machine-generated content.
+
+Zero classes. No `.btn`, no `.card`, no `.container`. Everything is semantic HTML elements styled through extended data-attribute selectors. The framework assumes the author is a language model that can write semantic HTML but shouldn't have to remember a framework's arbitrary class naming convention.
