Heartbeat Skyline — 5 Variations

Pure line. The EKG becomes a skyline — building heights as pulse spikes. Minimal, elegant. The tallest spike is the anchor point. No fill, just the stroke.

Line + gradient fill underneath. More presence than pure line. The glow dot on the tallest peak says "pulse, alive, now." The fill fades to transparent at the bottom.

Contained mark. Gradient circle with white pulse skyline inside. Works as app icon directly. Strong at small sizes. The most "logo-like" — self-contained, no bleed.

Home + heartbeat. The tallest EKG spike IS the rooftop. Subtle house body below. More "neighborhood" than pure skyline. The house only appears at larger sizes — degrades gracefully to just a pulse.

Ready-made app icon. Rounded square with the pulse skyline inside. Combines C's containment with B's fill. Works as favicon, app store icon, and header logo. The most production-ready option.
