Type protocol / 05
Typography
Three open-font roles create a wide title rhythm, condensed operational labels, readable body copy, and disciplined telemetry without redistributing font files.
01 / ROLES
One family system, four jobs
The stack is selected by function. Avoid using the display face for paragraphs or the mono face as generic “science-fiction” decoration.
Pressure cycle
Space Grotesk
Paragraphs, forms, descriptions, and long documentation passages.
101.3 kPa
IBM Plex Mono
Telemetry, code, checksums, timestamps, units, and terminals.
02 / TITLE CUE
Segmented reveal without copying a logo
The lockup uses tracked, horizontally resolving letterforms as an original interface motion cue—not a reproduction of the film title artwork.
Incoming transmission
SIGNAL
Motion / 980 ms + 55 ms mirrored stagger
03 / HIERARCHY
A compact operational scale
Display sizes use fluid clamps; labels and data remain stable so dense controls do not change rhythm across viewports.

Letters, numerals, and telemetry punctuation
Use specimens that expose ambiguous forms before selecting fallbacks or replacing a project font. Tabular numerals remain aligned in changing data.

05 / IN CONTEXT
Procedure, control, and data examples
Typography is judged in real combinations: a compact label beside an input, a readable procedure, and aligned telemetry under pressure.
Equalize the chamber
Confirm both hatch indicators are locked. Start the pressure cycle and remain at the control station until the differential reads zero.
Do not bypass the automatic isolation interlock.

Override font delivery without changing components
All typography classes resolve through four custom properties, making licensed self-hosting or system-only deployment straightforward.
