Wireframe Annotated.

An annotated / redline lo-fi wireframe of a desktop landing page — greybox blocks inside a browser frame, numbered annotation pins (①–⑤), and a right-hand spec panel mapping each pin to a short engineering / UX note. Use when the brief asks for "annotated wireframe", "redline", "wireframe spec", "lo-fi landing", "low fidelity", "线框图", or "标注线框".
