Selected direction: Signal Stack
Signal Stack is the sole active Bobby Inbox brand direction. This page shows the refined mark and wordmark applied across lockups, colour surfaces, sizes and interface previews. All gradients have been removed and the accent is one flat, canonical yellow.

- Yellow usage. #FFD600 is the single accent: status dot, primary emphasis, one call-to-action per view. Never tinted toward green, lime, chartreuse, mustard or orange, and never faded into a gradient.
- Yellow contrast rule. Text and icons on yellow are black or deep aubergine (#2A1030) only — never white.
- Typography. Space Grotesk for the wordmark and headings (Bobby bold, Inbox medium, −0.02em tracking); DM Sans for interface and body text. Title case “Bobby Inbox” everywhere.

Concept
Three descending rows read as a conversation list resolving from volume into order; the single yellow disc marks the item routing has pushed to the top. Refinements in this checkpoint: consistent 9px row height and 4.5px radius, even 6.5px gutters, the dot optically aligned to the top row terminal, and a simplified micro build below 24px so the status indicator never blurs.
