/**
 * Role-based profile accents (instructor vs student).
 * Option A: soft tint fill + primary-color border (instructor: 2px, student: 1px).
 * Shape: both circular; weight differs for grayscale / non-color cues.
 *
 * Example (standalone initials chip):
 *   <span class="ll-role-avatar ll-role-avatar--md ll-role-avatar--instructor" aria-hidden="true">
 *     <span class="ll-role-avatar__initials">AB</span>
 *   </span>
 *
 * Example (titlebar / hub host — classes on existing button):
 *   <button class="titlebar-avatar-button ll-role-accent--instructor" type="button">...</button>
