prevents quick pointer flyovers from flashing the tooltip.

/* Touch-only devices: tooltip only appears in the Copied state
(triggered from JS on tap), stays stable, then fades out.
- text swap / label transitions are killed so the tooltip
fades in already reading "Copied" instead of cross-blurring
from "Copy code" mid-reveal.
- .tt-swap width is pinned to the Copied width (--tt-w-b)
in every state so the pill is born at the final size and
never snaps between widths when the attribute flips.
This block MUST come after the base .tt-swap / .tt-label rules
above — equal-specificity selectors are resolved by source
order, so placing the override earlier silently lets the base
`width: var(--tt-w-a)` / `transition: width 240ms` win. */
