/* ── the profile control · SOLE DEFINITION ───────────────────────────────────
   One circle, two contents, IDENTICAL on all 82 pages.

   SIZED TO THE THEME TOGGLE beside it, which measures 34px tall: `.toggles` is a 1px
   border plus 3px padding around a 30x26 `.tg`. This is 34x34, so the two controls read as
   a matched pair rather than one looming over the other.

   TAP TARGET is extended to 44px by the ::after, exactly as `.tg` does with
   `inset:-9px -2px`. A 34px visual with a 44px target satisfies WCAG 2.5.8 without making
   the header furniture bigger — shrinking the box and shrinking the target are different
   things, and only the first was asked for.

   SELECTED BY ITS DATA ATTRIBUTE ONLY. The markup used to carry `class="k-chip"`, which
   kids.css owns for the honey filter chips at `padding:0 15px`. Same specificity as an
   attribute selector, and kids pages load kids.css second, so on those pages the padding
   survived and squeezed the avatar into an ellipse. si16_chip_chrome no longer emits that
   class. Do not add a class to this control: a class can be claimed by another component,
   a data attribute in practice cannot. */
