/* Opus Hub — app styles. Values are the canvas's (Opus Hub.dc.html, artboards of turns 2–5),
   lifted into the token names of css/tokens.css (UI spec §1, §9). Type sizes go through --u so they
   are exact design pixels at the default text size and follow the user's text-size setting.
   Phone first; the desktop layouts (single column 700–1100, grid above 1100) arrive in step 4 —
   until then every width shows the phone column, centred. */
