/* IAL Maths Lab — v057
 *
 * Phone handoff (scan → photograph → it lands on the tablet) and the paper
 * archive. Same rules as the rest of the chain: nothing here is a media query,
 * because the interface can be zoomed to 150% and a media query would still be
 * reading the unzoomed width. Grids use auto-fill so they reflow on their own.
