`all` also sped up Run's mode colours, Stop's confirming state and the armed Ctrl key. The browser test now reads the transition at rest, since its 250ms hold would also pass the old 0.2s one.
On every skin but og the skin block outranks the phone :active backgrounds of the toolbar buttons, so Run showed no press at all and the others at most a faint tint, eased in over their 0.2s transition, so a quick tap showed almost nothing. A press now scales and brightens (darkens on the light skins) over 80ms, two properties nothing on these buttons sets at a higher specificity, and honours prefers-reduced-motion.
A browser test presses every phone bar control on all seven skins and pins the computed transform and filter, so a later rule that takes the press away again shows up in the browser suite.
