/* ============================================================================
 * Spectrum.js (kartik\widgets\ColorInput) — ui-refresh modernization
 *
 * Spectrum injects its picker as a child of <body>; since `.ui-refresh` lives
 * on <body>, scoping under `.ui-refresh` cleanly upgrades only ui-refresh
 * pages while legacy surfaces keep stock Spectrum.
 *
 * IMPORTANT: Spectrum's saturation/hue/preview boxes are absolute-positioned
 * with pixel dimensions computed by JS at open-time, and `.sp-container`
 * itself uses `box-sizing: content-box` for all children. Touching either
 * `.sp-container`'s padding or any of those absolute-positioned children's
 * borders / overflow can collapse the picker. Stay on outer chrome + the
 * independent inner elements (swatches, input, buttons).
 *
 * Specificity: one class deeper than the vendor's `.sp-krajee ...` rules,
 * so overrides win without `!important` — except where the vendor itself
 * uses `!important` (sp-cancel color).
 * ========================================================================= */
