Page cataloging legacy and alternate Octocat/mascot styles (Octocat 1.0, 2.0, Monamoji, Outline) with thumbnails, three marked as not-default with red icons.
Summary
A reference page for the brand's alternate and historical mascot styles, presenting Octocat 1.0, Octocat 2.0, Monamoji and Outline style as thumbnails with notes, several flagged as not the default.
Visual description
A left intro explains these styles represent past eras and shouldn't be the default but may appear for history or internal moments. The body is a two-column grid of four entries, each a monospace title, a paragraph, and a thumbnail: OCTOCAT 1.0 (the flat black-and-cream octocat, red no-entry overlay), OCTOCAT 2.0 (a colorful 3D narrative scene), MONAMOJI (a grid of octocat emoji faces, red overlay), and OUTLINE STYLE (a dark neon line illustration, red overlay). Standard header and green rule above.
Key takeaway
Documenting deprecated and special-case styles in one place, each clearly marked with a prohibition icon when it isn't the default, so the brand's history is preserved without inviting misuse.
Reuse notes
Useful for mature brands with legacy assets people still reach for. The mix of small thumbnails plus a red flag is an efficient way to say "this exists, but not by default."
