To preserve computational scholarship, a durable method is needed to package data, analysis, and visualization into a single, executable artifact. Current approaches, however, rely on a fragile ‘wet-nurse’ model of external dependencies: APIs, frameworks, and platforms that inevitably deprecate, churn, and sunset. This paper proposes a zero-dependency HTML architecture, a ‘digital paratype,’ that is born weaned: it runs in any standards-compliant browser, with no runtime installation or external fetches
