The wordmark is the logo. An italic ember slash becomes the hinge between "I" and "O" — the literal shape of input/output, set in Instrument Serif. Three directions shown below; Direction A is live.
The wordmark is the logo. No competing mark — the italic ember slash between "I" and "O" is the whole identity. Editorial, confident, unmistakably us. For tight spaces (favicon, avatar) we use an "I/O" glyph derived from the same type.
Two squares — input and output, offset. Reads as a logic gate, a handshake, a migration. On the bench as a more technical / developer-forward alternate.
The favicon and avatar derivative. Just "I/O" in Instrument Serif with the same italic amber slash. Used wherever the full wordmark is too wide to read — browser tabs, social avatars, app icons.
A tight palette built around contrast: obsidian for authority, bone for clarity, amber for the spark. Everything else is restrained grayscale.
A serif that carries the brand. A sans that carries the work. A mono that carries the data. Pairing gives Spark I/O an editorial confidence without feeling precious.
Spark I/O talks like a senior operator who respects your time: direct, warm, allergic to jargon. Never corporate. Never cute.
Every surface of Spark I/O is built from a tight set of primitives. Pills not corners. Editorial stats not dashboards. Grid-driven spacing.
Motion reinforces hierarchy — never decoration. Three easings cover 95% of interactions. If something moves, it should be answering a question.
