How this site is made

Updated

Praxis uses Source Serif 4 and Source Sans 3, with a self-hosted Arabic companion face. The site is built with Eleventy and delivered through ChatGPT Sites. Its figures are generated from code at build time.

The home lens uses five Robinson-triangle subdivisions from a ten-triangle wheel. Sheet P-01 uses six subdivisions and retains complete rhombi inside a circle. Shared vertices and edges are deduplicated before the Voronoi diagram, Delaunay triangulation and shortest path are computed. The pentagrid is a separate illustrative construction. Sheet P-02 uses an illustrative directed dependency graph and computes earliest starts, latest starts and slack.

The site targets WCAG 2.2 Level AA and tests contrast, keyboard operation, reduced motion and static content. Automated checks do not establish complete accessibility compliance. Spanish and Arabic pages were checked by machine-assisted comparison with the English text; they have not been reviewed by a native speaker. Screen-reader and physical-device review results will be noted here when completed.

Scripts and fonts are self-hosted. An enforced Content Security Policy and HTTPS security headers protect delivery. Performance measurements retain weekly anonymous ranges, not visitor profiles. Each published claim is mapped to an owner statement or source record before release; owner-attested figures are not independently audited.

Focus a tile and use the arrow keys to inspect vertex coordinates.

Note: counts cover complete rhombi inside the radius. The pentagrid is an illustrative construction, not an exact dual of this patch.

Sheet P-02 · Critical path: an illustrative dependency model for funding, finance, systems and delivery.
Illustrative award dependency graph with Funding, Finance and Delivery on a ten-day critical path.

Illustrative durations, not a schedule or service commitment.
