/* Estudio - mobile first, touch first.
 *
 * Rules this stylesheet keeps:
 *   - every tappable thing is at least 44px, because she is using a phone
 *     one-handed and a missed tap costs money
 *   - the action bar is sticky and always shows the cost before she commits
 *   - dark, because the content is photographs and a bright chrome fights them
 *   - no framework: this is seven chip rows and two image grids
