Enact / Brand System / Wave 4

Social media kit

Avatars + headers/covers + post + story templates for the five primary platforms — Twitter / X, LinkedIn, Facebook, YouTube, Instagram. All in the locked palette, all using the existing logo system. Same brand, every surface.

Avatar

Three options. A · Signal flood with a Carbon "E" is most distinctive at small scales (where most platforms render avatars). B · Carbon block with a centered Signal block is most brand-strict. C · Paper mark shows the lockup compact — works only at larger sizes. Use A on Twitter, LinkedIn, Instagram (where avatars render at 32–48 px in feeds). Use B for YouTube and Facebook (where avatars are larger). Use C only for cases that allow rectangular avatars.

LinkedIn · header

1584 × 396 · 4:1 aspect. Wider than Twitter, so the tagline gets more breathing room. Same three variants, adjusted for the proportion.

Brand-coherence rules per surface

One Signal accent per asset. The Signal block in the lockup counts; nothing else on the page should be Signal yellow.

Default background per platform: Paper for Twitter / LinkedIn / Facebook / IG-thesis. Carbon for IG-stat and the YouTube tagline cover. Signal flood reserved for launch moments only — not for ongoing posts.

Type: Geist Bold for wordmark and headlines. Geist Regular for taglines. Geist Mono for meta lines and stats. Never Geist Mono for body — only operational moments.

Avatar selection: use A (Signal flood with E) at every platform where avatar renders at 48 px or smaller in feeds. Use B (Carbon block) for YouTube. Use C only where rectangular avatars are allowed.
