Make --radius-avatar the single source of truth for frontend user avatar shape. A new primitive in components-ext.css (img.avatar / avatar-mini / avatar-md / avatar-lg / .avatar-img img) forces a circle on every avatar image, which covers the bare avatar-mini in the ban and report modals, the classless img inside the VIP modal's .avatar-img, and the post-card meta avatar that previously depended on post-card.css being enqueued. The user center header frame, the public user home hero and the friends page avatar switch to the same token because route CSS loads after the public bundle and would otherwise override the primitive.
The VIP icon no longer rides the avatar corner. The user card widget, the after-article author card and the sign-in modal stop opting into aksrt_get_avatar_box()'s corner badge, and the icon renders first in the badge/level row instead, since aksrt_get_user_name already orders name -> VIP -> auth -> medal -> level. The sign-in modal appends it after the display name and keeps the legacy precedence where a ban badge takes the VIP slot. The user card widget name row now shrinks its display name so the extra icon cannot overflow a narrow sidebar.
Verified with the new frontend-avatar-shape-contract test plus post-visual, user-card-runtime, circular-button-icon-margin, user-features and page-display contracts, and php -l on every changed PHP file. The public bundle was rebuilt with tools/build-public-assets.mjs.
.aksrt-wave was injected into .but without position:absolute, so the
oversized span expanded header publish/VIP buttons on click. Make the
wave absolute, honor .nowave, and skip navbar CTA roots.
