5 * ClaudeHeader — Claude Code's welcome box.
6 *
7 * The title-in-the-border is a real <fieldset>/<legend>, so it stays semantic
8 * and inherits whatever background it sits on. The logo is Claude Code's own
9 * pixel sprite, but drawn as a crisp SVG grid instead of quadrant-block glyphs
10 * — no font seams, scales cleanly.
