/* adhno — arcade design system.
 *
 * Loud on purpose. The counterweight to a task list that otherwise feels like a
 * chore is a screen that looks like something worth opening.
 *
 * Two rules run through all of it:
 *   - Red is never used for an unfinished task, only for destructive actions.
 *     Nothing on the home screen should read as "you failed".
 *   - The pixel/display treatment decorates numbers and headings only. Task
 *     titles and body copy stay in a plainly legible face, because ADHD often
 *     travels with dyslexia and a hard-to-read task is a task that doesn't get
 *     started.
