/* skbpa:product.assistant — «Онлайн-помощь».

   A compact support window, not a full-screen modal. On desktop it docks to the
   bottom-right in the shape people already read as "live help", leaving the
   product page visible behind it; on phones it takes the viewport because
   anything smaller is unusable with a keyboard open.

   Visual register is deliberately industrial-professional: one restrained
   accent, no gradients, no avatars, no "AI" glow. It should look like SKB
   technical support, not a consumer messenger. */
