/* BLOX O₂ - mobile styles
 *
 * Built on the Quasii Chrome extension's design system (sidepanel.css): same
 * variable names, palette, components and dark theme, so the two read as one
 * product. The extension draws at a compact desktop scale (13px body, 24px
 * hit targets); a phone needs the opposite, so the radii, spacing and type
 * scale below are stepped up for touch while every colour stays the same.
