Ink Paper Soft blue C1E5FF Bright cyan 6FDEF7 Signal lime E8F87E

Lime is a signal. A find, a match, a moment of intelligence. Never furniture.

Type. SF Pro. Display alt: Founders Grotesk where licensed. No decorative faces.

Spacing. Generous negative space; overlay text keeps a 7% safe margin from every edge.

Logo. Wordmark bottom-left inside the safe margin, paper on dark, ink on light. Clear space: the height of the F on all sides.

Imagery. Premium tech editorial. Never medical or clinical staging; the facelift layer is retired.

What's working

Results attach to creative IDs; patterns are learned from style fingerprints. A future campaign import writes into the same shape, so nothing here gets rebuilt.
