— design principle no. 1 · tux foundations

foundations

Three commitments.

01 · VOICE

Institutional, not instagrammable.

Research-agency feel. Specificity over marketing language. We name the classifier version, the ITAR bucket, the exact grant number — not vague metaphors.

02 · DENSITY

Information over decoration.

Dense data tables with one-token spacing. Oversized editorial numerals for summary stats. No hero illustrations, no dashboards that look like magazines.

03 · DURABILITY

One engineer, five apps, ten years.

Decisions biased toward low-maintenance. Self-hosted fonts. No bespoke animation libraries. Themes layered on CSS variables, not rewritten per-institution.
