/* ==========================================================================
 * Everything below is inside @layer upline.
 *
 * This is the ownership line made structural rather than habitual. By the
 * cascade specification, a normal declaration in ANY layer loses to an
 * unlayered one, whatever the selectors say -- so a theme's plain
 * `.upline-menu__link { color: red }` beats anything in here without needing
 * to out-specify it, and a theme author never has to count our classes or
 * reach for !important to restyle a surface.
 *
 * The reverse holds for important declarations: layered !important beats
 * unlayered !important. So the few guards that genuinely must not lose --
 * the breakpoint that keeps navigation off a click, the visually-hidden
 * utility, reduced motion -- get *stronger* here, not weaker. That asymmetry
 * is the reason this is the right mechanism and not merely a tidy one: it
 * makes feel a theme's to take and mechanics ours to keep, by construction
 * rather than by everybody remembering.
 *
 * Browser floor: @layer is Safari 15.4+, Chrome/Edge 99+, Firefox 97+ (all
 * March 2022). Below that the whole block is dropped as an unknown at-rule
 * and the surface renders unstyled -- which is why the floor is stated in the
 * release notes rather than left to be discovered.
 * ========================================================================== */

 * The motion gate: one place, so reduced motion cannot drift.
 *
 * These three are internal plumbing, not tokens -- they are not in
 * docs/theme-tokens.md and a theme has no business setting them. They exist
 * because the reduced-motion guard used to be a second copy of the component
 * selector list, and the two copies had already drifted: the base motion
 * declaration covered ten selectors, the guard covered three, so seven
 * surfaces kept moving for someone who had asked their operating system for
 * stillness. That is the doc's strongest promise broken by a list nobody
 * remembered to grow.
 *
 * A gate declared once at :root and consumed by every component declaration
 * cannot drift, because there is no second list to forget. Adding a surface
 * gets reduced motion for free.
 *
 * :root works here precisely because nothing re-declares these -- the same
 * inheritance rule that makes a shop's `:root { --upline-* }` override fail is
 * what makes this reach every surface.
