/* DXN Studio site theme.
 *
 * Palette and proportions come from the publisher ident that plays on cold
 * launch of the studio's apps: spec/timings.json in dxn-studio-splash for the
 * field and word colours, design/DXN Studio Logo.dc.html for the lockup.
 *
 * Two colours from the brand files are deliberately never used as text here:
 * #3b3a63 is 1.80:1 on the field (it is the LIGHT-mode word colour) and the
 * #4b3fd6 violet is 2.72:1. Both fail AA. The gradient is for rules and
 * accents only.
