• Rewrite _docs.ts to use Hono JSX (no html strings) and twind for css.
• Fix the readFile type to take two strings and return a Promise of string or undefined.
• Audit all the type signatures of all the functions and replace any with better types
• Add ts syntax highlighting for the function signature and the example. Strip the ts from the examples
• Add precise type information for all inputs and outputs. Users should know exactly every field of every input and every output type.
• The note about file-system access belongs both at the top of the docs and also briefly mentioned in the readfile and listfile functions too.
• (For later) Augment the docs generator with test information.
