VisualChem
Bilingual, scroll-driven chemistry stories in which the macro, micro, and symbolic views are driven by one computed state, so nothing on screen is a pre-drawn picture pretending to be a model.

Projects
Project stories explain why a piece of software exists and where its boundary is. The catalog below accounts for every public repository, including forks and meta repositories, so nothing is hidden and nothing is inflated.
Stories
Project stories
Long-form pages for projects that benefit from explanation. Code and current state live in the repositories.

Agent infrastructure & developer tooling
Tools that let editing agents work next to privileged browser, Git, and cloud state without holding it.
-
texpage-bridgeactive
A local broker that compiles Git worktrees on a TeXPage-compatible cloud compiler while keeping browser sessions, Git credentials, and signed URLs away from editing agents.
-
A fail-closed supervisor for long-running browser-driven agents: durable task registry, reconciliation, worker leases, and replay-safe recovery.
