/*
 * One file per alphabet for every weight.

 * Rubik here is a variable font: the 400, 500 and 600 files were byte-for-byte
 * the same file under three names, so a screen with ordinary text, a name and a
 * heading fetched it three times and swapped the text in three separate
 * moments. The three rules stay, so weight matching is exactly what it was;
 * they now point at one url, and the browser fetches it once.

/*
 * What text is drawn in before Rubik arrives, shaped like Rubik.
 *
 * Until the file lands the browser draws with the next font in the list, and
 * that font's lines are taller: Segoe UI takes 1.33 of the font size to
 * Rubik's 1.185. When Rubik then arrives every line gets shorter at once, and
 * in the chat that is every message on the screen moving - 43px on a stand
 * with twenty bubbles. The overrides below give the stand-in Rubik's ascent,
 * descent and width, so the swap changes the letters and nothing else.
 *
 * Only for the characters Rubik itself covers; anything outside that goes on
 * to the system fonts exactly as before. Browsers without these descriptors
 * (Safari) simply do not use the tuning.
