+ // Bjørn is principally built to be run from the command line (as a

+ // patterns. However, it recognizes hooks through various
+ // specially‐named properties on `globalThis`. After defining these
+ // hooks, a script can use a *dynamic* `import("./path/to/build.js")`
+ // to run the Bjørn build steps.
+ //
+ // To make writing scripts which make use of these hooks easier,
+ // infrastructural dependencies and useful functions are provided on
+ // `globalThis` so that wrapping scripts don’t have to attempt to
+ // manage the dependencies themselves.
+ //
+ // Note that the `Lemon/window` polyfill will already have
+ // established some D·O·M‐related global properties by the time this
+ // runs, so they don’t need to be redeclared here.
