/* IRONCADE MOTION FOUNDATION - motion.css
   ruleVersion: motion-1.0

   This file does not introduce a new design language. Every token below was
   measured out of styles.css as it already ships. The point is to give the
   values that are already in use a NAME, so that the next screen built uses
   the same number instead of a new one.

   Inventory that produced these tokens (styles.css @ build 86):
     .09s  x1   transform/filter on .addex           -> instant
     .12s  x27  the de-facto house duration          -> fast
     .15s  x2   background, pin dots                 -> fast
     .2s   x2                                        -> standard
     .22s  x1   @keyframes fade (screen enter)       -> standard
     .26s  x2   #pinGate opacity, pwaUp              -> emphasized
     .28s  x1   with cubic-bezier(.3,1.6,.5,1)       -> emphasized + arcade ease
     .35s .5s .7s  width on data bars                -> data

   NOTHING IN THIS FILE IS APPLIED AUTOMATICALLY except the token
   declarations themselves and the reduced-motion safety net. Classes are
   opt-in so that shipping this file cannot change how the live app looks.

   PRESSED STATE STANDARD

   The audit found 14 pressed rules using 6 different scale values:
   .92 .96 .97 .975 .98 .99. A control's size should not tell you which
   file it was written in. One value, one duration, applied by adding
   class="press" to the element.

   Scale .97 is the median of what already ships and reads as a press on
   a 44px target without looking like a bounce on a 72px one.

   Existing :active rules are deliberately NOT overridden here. They are
   migrated screen by screen in a later phase, so no surface changes
   appearance the moment this file loads.

   TEXT SELECTION GUARD  (iOS long-press callout on controls)

   The brief is explicit: do not apply user-select: none globally.
   There is a concrete reason in this codebase. styles.css:802 sets
   .wl-crew-id { user-select: all } - that is the CREW INVITE CODE.
   A global guard would make invite codes uncopyable and quietly break
   the way people join a crew.

   So: the guard is a list of chrome and control surfaces, and there is
   an explicit opt-out that outranks it.

   REDUCED MOTION

   Before this file there was exactly ONE prefers-reduced-motion rule in
   the whole app (styles.css:678, covering .pwa-sheet-card and .pwa-cta).
   Everything else animated regardless of the setting.

   Reduced motion means reduced, not removed: state still changes, it
   just changes without travel. Opacity is kept because a thing appearing
   is information; transform and width travel are what cause trouble.
