/*
 * ============================================================
 * TESTIMONIALS — homepage "رضایت مشتری" section
 * A row of circular story avatars (css below) + a single shared full-
 * screen story viewer (markup lives once in index.html, content swapped
 * by js/testimonials.js). This component's "own small visual personality"
 * comes from its shape language (circles, segmented progress bars, a
 * per-testimonial ring color) rather than any new type system.
 *
 * The ring color is one of five tones defined below, scoped to this
 * component only (never added to css/tokens.css — this palette has no
 * other use on the site) — a dark-teal family anchored on #264D59, plus
 * one restrained warm complementary tone, deliberately controlled, never
 * a free/rainbow palette. js/testimonials.js assigns one, deterministically,
 * by hashing each testimonial's own id — every testimonial keeps the same
 * color forever regardless of list order, and the row is automatically a
 * coordinated set for 2 testimonials or 50, with nothing for an admin to
 * configure per person.
