/*
 * The step-by-step request picker (hs-core). A full-screen sheet on phones, a
 * centred panel on larger screens. Themes dress it through custom properties:
 *
 *   --hsc-picker-ink         headings and option words      (default: --hsc-main)
 *   --hsc-picker-accent      chosen option, progress, next   (default: --hsc-main)
 *   --hsc-picker-accent-ink  words on the accent             (default: #fff)
 *   --hsc-picker-soft        option background               (default: #f3f4f6)
 *   --hsc-picker-send        the WhatsApp send button        (default: #0a6c3f, white words 6.6:1)
 *   --hsc-picker-r1 / -r2    corner radii (a theme's leaf: big / small)
 *
 * RTL first: logical properties only.
