dynamic-surface.ts:13:38 - error SC2020: 'Number.prototype.toLocaleString at locale "de-DE"' is part of the standard library types but has no scriptc lowering yet

  12 | const tau = Math.PI * 2;
  13 | const price = (19.99).toLocaleString("de-DE");
     |                                      ^~~~~~~
  14 | const n = Number.parseFloat("3.14");

  hint: what lowers is the default locale (no argument) and the composed en-US form — other locales are ICU data the binary does not negotiate yet
