PACIFIC COMPUTE — X / TWITTER & SUBSTACK KIT
5 October 2026 · Edition 02

Open social/index.html to choose your platform and colour treatment.
The left column describes each file, its dimensions and background.
The right column previews the actual artwork. All files are in assets/social/.
Every image has an SVG master and a PNG export. SVGs are entirely vector
paths, including the lettering: there are no external fonts or raster images.
Use SVG wherever supported. PNGs are rendered directly from the exact SVG
masters at high resolution for platform uploaders that do not accept SVG.
No previously rendered PNG is enlarged. All avatars are 2048 x 2048; the
X banner is 4500 x 1500; remaining PNGs are 2x the SVG canvas dimensions.

PREFERRED BRANDING
Use the stacked P + Pacific / Compute logo. The P is 1.6 times the complete
lettering height, with the approved shapes and weight unchanged. Compact
single-line artwork is only for placements with restricted vertical space.
Never use the name on its own. P-only avatars include circle-safe padding.
Ink: #182F4A. Paper: #F7F7F2.

FILENAMES AND BACKGROUNDS
paper-solid = cream artwork on an included blue background.
ink-solid = blue artwork on an included cream background.
ink-transparent = blue artwork with no background.
paper-transparent = cream artwork with no background.
Final filename numbers are exact canvas dimensions in pixels.

Substack may call its header field "Wordmark"; our file includes the P and
complete name. Choose its Stacked header layout where available. Add the
footer image above the platform's automatic address/unsubscribe footer.
The source copy is the bio from the supplied X screenshot:
"Safety compute for the open frontier". No posts are supplied or published.
The preview page is illustrative; the platform determines its live layout.

Font licences are included for the preview. Artwork needs no fonts installed.
Keep the P and lettering together at the supplied aspect ratio.
