/* u_50_9: circle hardening for the mobile account avatar
 * -------------------------------------------------------------------------
 *  u_50_8 pinned the chip button at width:36 / height:36 and the avatar
 *  span at width:100% / height:100%.  In practice the button is a flex
 *  item of .topbar, so `min-height: auto` lets it grow taller than 36 px
 *  the moment anything inside it contributes more height — which turns
 *  the 50% border-radius into an ellipse.
 *
 *  This block makes squareness non-negotiable:
 *    • aspect-ratio: 1/1 on the button (square even if height is
 *      stretched by a parent)
 *    • align-self: center + flex: 0 0 36px (opt out of any stretching)
 *    • min-height: 0 (defeat the flex-item `auto` minimum)
 *    • padding / margin / border explicitly zeroed
 *    • the avatar span is absolutely positioned inside the button with
 *      inset: 0, so it fills the button's padding box exactly — no
 *      percentage arithmetic involved.
 *
 *  Result: 36 × 36 button, 36 × 36 span, 50% radius → perfect circle.
 *  On the 32-px breakpoint (≤ 420 px) it scales down in step.

 *
 * Elements that intentionally hide their scrollbars — the topbar, the
 * editor-tabs strip, the modal-tabs strip, the filter-chips strip,
 * the Python textarea's highlight overlay, the palette search field —
 * declare their hidden scrollbars with class-prefixed selectors,
