/**
 * Formula library (Direction B "Small" scope, per the owner-approved
 * proposal - see the "Formula Library & Special Character Picker" scoping
 * artifact): a curated set of common science/math formulas, browsable by
 * domain and searchable by name, replacing the raw `window.prompt`
 * formula-insert flow.
 *
 * Every entry's `latex` is plain LaTeX, verified against KaTeX 0.18's
 * supported command set (the actual rendering ceiling - see
 * `surface/renderer.ts`'s `KATEX_OPTIONS`, `{ trust: false, strict: "error"
 * }`). Chemistry entries use the `mhchem` extension's `\ce{...}` macro,
 * registered in `surface/renderer.ts` (core) for real document rendering
 * and in `FormulaLibraryPopover.tsx` for this library's own previews.
 *
 * `notation` is always `"latex"` - the schema also accepts `"mathml"`, but
 * the renderer never implements a MathML render path
 * (docs/bugs/formula-mathml-notation-not-rendered.md, open) - so no library
 * entry may use it.
