 * Bubble distinction — self / peer / bot
 *
 * Problema: em DMs e grupos com 2+ members + bot, todas as bubbles do tipo
 * "user" ficavam visualmente idênticas (mesmo gradient pink/cyan), tornando
 * impossível distinguir o que disse o próprio user vs o que disse o outro
 * member. Resolvido cruzando state.user.member_id com msg.sender_member_id.
 *
 * - bubble-self: pink/cyan gradient (mantém o look familiar do user actual)
 * - bubble-peer: roxo→magenta (distinto mas complementar; alinhado à esquerda)
 * - bubble-bot:  dark com border accent + ✨ (claramente "não-humano")
