A unit test for Gettext translations that checks if the original and the translation use the same HTML tags. Uses Floki to parse HTML.

TypeScript notes
// If I define a union type of strings and want to use it as a type for object keys:
type Food = 'Banana' | 'Berries'
const calorieCounts: { [index in Food]: number } = {} // <- NOT `index: Food`
// ----------
// If I define an object and want to use its keys as a type:
// NOTE the object shouldn't have a type definition for this to work!
const planetYearsToEarthYears = { earth: 1, mercury: 0.24 }
type Planet = keyof typeof planetYearsToEarthYears
