Brand
A sun-baked, clay-toned editorial interface built on warm cream surfaces, ink-brown headlines set in a display serif, and a single terracotta accent. Earthy, human, and content-first — tuned for long-form reading, blogs, storytelling, and editorial layouts where readability and visual rhythm matter.

Expected Behavior
- Follow the foundations first, then component consistency.

- Keep guidance opinionated, concise, and implementation-focused.
Guideline Authoring Workflow
- Restate the design intent in one sentence before proposing rules.
