   (the floating toggle and the empty-state greeting), and the original,
   more graphic/high-contrast bitnnock-nock-avatar.png at the two small
   sizes (the 22px header icon and the 26px per-message avatar - also
   what data-avatar points JS at for dynamically-created message rows).
   The hero render's finer, lower-contrast photoreal shading tested
   genuinely worse at 22-26px (the glowing visor nearly disappears) than
   the original's bolder, simplified lines - confirmed by rendering both
   down to real size before choosing, not by eye at full size. Don't

   this project's HIG-based design rule on protecting attention), with a
   distinctly faster, stronger pulse reserved for when Nock is actually
   working on a real request so the animation's intensity communicates
   live status, not just decoration. :has() (not a JS class toggle)
   drives the reactive state: the per-message avatar reacts to its own
   row's bubble carrying .bn-nock__msg--pending, and the floating toggle
   reacts to a pending bubble anywhere in the whole widget, so it keeps
   signaling "working" even if the panel gets minimized mid-answer. */
