D1 — sharpest conceptual idea. The dot in .online is a micro floor plan. Nothing added, everything earned. Best for a brand that wants to feel clever without trying.
C3 — most production-ready. Filled gold mark + bold/light weight contrast. Ships tomorrow, holds up at every size.
E2 (op.) — strongest short form. Three characters, gold period. Works huge on a hero and tiny in a mobile nav.
F4 — best app icon / favicon. Gold square, floor plan grid inside. Clear at 32×32px.
G4 — best nav-bar solution. offplan large + .online as a chip tag — doesn't compress into mush at 14px.
G1 (circle stamp) — most distinctive, hardest to use daily. Great for watermarks, press kits, certificates.
