 * 2023 shadcn), copied on 2026-10-02 (ADR-0014). Changes:
 * - data-[side=left|right] become data-[side=start|end] with
 *   slide-in-from-end|start: Ndop sides are logical (RFC-0001);
 * - origin-(--radix-tooltip-content-transform-origin) is dropped: the CDK
 *   overlay sets no such variable;
 * - no arrow: the primitive doesn't position one;
 * - timing follows the primitive's contract (700 ms to open on hover,
 *   immediate on keyboard focus) rather than shadcn's instant default.
