/* ================================================================ THE POLISH LAYER
 *
 * Loaded LAST, after every component sheet and after mobile.css, and it owns exactly one thing:
 * the FEEL that is common to every interactive element and therefore cannot live in any one
 * component's sheet without drifting. Four laws, each stated once:
 *
 * 1. ONE MOTION BUDGET. Everything that answers a pointer transitions its paint (ground, ink,
 *    rim, shadow) over --t-tap on --ease, and everything that arrives as a surface keeps the
 *    pop-in its sheet already gave it. A control that answers instantly beside one that fades
 *    reads as two products; the union of properties lives here so a component's own narrower
 *    transition list can never silently drop a property a sibling still animates.
 *
 * 2. ONE PRESS. Every pressable thing dips - scale(.98) under the finger or mouse for the length
 *    of the press and back on release. Tactile feedback is the difference between a control and
 *    a label; the dip is the smallest honest version of it. Elements that carry their own
 *    transform for state (folded chevrons, drawn knobs) are children, not the button, so they
 *    are untouched.
 *
 * 3. ONE NUMERIC FACE. Digits that update - tick fields, period chips, PnL cells - set in
 *    tabular figures, so a 1 becoming a 7 does not wiggle its neighbours. Anywhere the width of
 *    a changing number is layout, this is the rule it gets.
 *
 * 4. QUIET BY DEFAULT UNDER REDUCED MOTION: every rule this file adds that moves something has a
 *    prefers-reduced-motion answer, because a trading tool that ignores the platform's motion
 *    setting is arguing with its owner.
 *
 * What deliberately does NOT live here: colour (the palette owns it), layout (the sheets own
 * it), and close animations (a disappearing surface must be kept alive by script to fade out -
 * that is openWindow's change to make, not a stylesheet's to fake).
