 * PitStop -- public/css/name.css

 * rating sheet; tokens from base.css with safe fallbacks.
 *
 * Layer: 1350 -- opened from the detail sheet (1200), so it must outrank it,
 * and it must sit UNDER the card sheet (1400) which can also be launched from
 * detail. The one authoritative ladder is the comment in install.css.
 * Explicit z-index, not DOM order.
