/* ============================================================================
   scrollcraft.css: the taste floor
   ----------------------------------------------------------------------------
   Two layers, and the split matters:

     TOKENS   what you override per brand. Colour roles, the type ramp, the
              spacing scale, elevation, motion. A brand is ~12 values.
     DEVICES  what the engine drives. Do not restyle these to taste; they are
              the mechanism. Style your own markup instead.

   Nothing here draws a "component". There are no card, badge, or pill classes,
   because a stylesheet that ships those is how every page built on it ends up
   with the same shapes. You get a floor and a vocabulary; the composition is
   yours.

/* ══════════════════════════════════════ the copy on a touch device, and LAST
   These three rules have to be the last word in this file, and that is the
   whole point of where they are.

   They were written on 20 September, in the coarse-pointer block near the top,
   and they never took effect. `[data-sc-cue] { opacity: 0; will-change:
   opacity, transform }` and `.sc-split__i { ... will-change: transform,
   opacity }` are declared FURTHER DOWN this same file at the same specificity,
   so they won on source order; and `.sc-ready [data-sc-cue] { transition: none
   }` outranks a bare `[data-sc-cue]` outright. So the hints stayed, and the
   cue's cross-in never ran at all. Measured on an iPad-sized WebKit with a
   coarse pointer: /summit/ had 25 promoted elements, and the largest group was
   TEXT -- five `p.small`, five `.sc-split__i`, two `p.say`, one `p.note`, all
   of them carrying `will-change: opacity, transform` and each therefore its own
   composited layer. /about/ had eight, none of them text; /partners/ and
   /privacy/ had none. That is the whole difference between the page Edgar says
   shakes and the pages he says are fine.

   It matters because iOS re-rasterises composited text at fractional positions
   while the page scrolls under it. The layer's position is rounded on its own,
   independently of the content around it, so the type appears to tremble
   against a page that is itself moving perfectly smoothly -- and at a slow
   scroll you are looking at one block of type long enough to see it, while at
   speed you are not. Edgar, 21 September 2026: "When the text appears strip the
   movement of it and see if that changes it."

   So on a touch device the copy is not promoted and nothing about it is
   animated: it is simply there when its act arrives. `html:not(.sc-layers)`
   and `html:not(.sc-fade)` raise these to (0,2,1), above everything they have
   to beat, and give a device two positive controls: ?sc-layers puts the
   compositing hints back, ?sc-fade puts the cross-in back. If either brings the
   shake back, that is the answer, said the other way round. */

  /* ── and no position changes either, which is the rest of the same answer.
     Edgar, 22 September 2026: "Can you remove the motion on the ipad version
     please." These are the reduced-motion rules from the middle of this file,
     verbatim in effect, handed to a touch device as well: "Fewer and gentler,
     not zero. Opacity still carries the reveal so the page is comprehensible;
     every position change is dropped." What remains on entry is a 220ms fade,
     and nothing anywhere rises, slides, wipes or drifts.
     ?sc-motion puts all of it back. */

  /* NOT [data-sc-pan], deliberately, and this is the one place the reduced
     block cannot simply be copied. Its own comment says why: "A rail's
     transform IS its navigation, not decoration. Zeroing it ... parks the act
     on its first screenful and makes everything past the fold unreachable: a
     device degrading into missing content." Reduced motion pays for zeroing it
     by turning the stage into a real scroll region with snap points. That
     pairing is a change to how the page carrying it is OPERATED on a touch
     device, and it needs its own check that every card stays reachable, so it
     is left alone here rather than smuggled in behind a motion fix.
     The rail is on /about/ -- the only page under site/ with [data-sc-pan],
     four acts of it -- not on /summit/programme/, whatever the note in
     05-Brand-and-Web/CLAUDE.md said. Verified still panning on a tablet after
     this change: matrix(1, 0, 0, 1, -636, 0) at the foot of its act. */
