/* 15/08/2026 — No celular, dois botoes de profundidade eram desenhados FORA do

   `grid-template-columns: repeat(2, 48px) !important` abaixo de 400px, contra
   `repeat(4, 48px)` do canone deste repositorio. A linha `.chat-composer-profile`

   ela transbordava 28px. A ancora de tres IDs abaixo foi criada para vencer a
   borda com quatro colunas de 48px.

   21/08/2026 — A linha de profundidade deixou o painel e, em telas de toque, cada
   item passou a mostrar nome e descricao (bloco "O menu Adicionar precisa
   distinguir cada ferramenta", no fim desta folha). A mesma ancora de tres IDs
   continuava impondo quatro colunas de 48px abaixo de 400px — e, por ter mais
   especificidade que o bloco de toque, espremia os rotulos em 48px: medido em
   375px no build do tip, 13 dos 14 itens vazavam de 53px a 93px para fora do
   proprio botao e os botoes chegavam a 150px de altura. A ancora permanece, pois a
   borda v12.2 ainda envia `repeat(2, 48px) !important` com dois IDs, mas agora
   entrega a grade que o bloco de toque pede: duas colunas fluidas ate 400px e uma
   so coluna ate 360px. */

   nunca conseguia subir acima do campo, por mais alto que fosse o proprio
   z-index: quem decide e o contexto de empilhamento do ancestral.

   Medido ao vivo no desktop: o painel terminava em 1137px e o textarea
   comecava em 1103px — 34px de sobreposicao, e nos 12 pontos amostrados
   dessa faixa quem pintava era o TEXTAREA. Como a linha de profundidade
   (Rapido / Equilibrio / Profundo) e a ULTIMA do painel, ela caia inteira
   nessa faixa. Daí os tres sintomas relatados como se fossem defeitos
   diferentes: o texto do campo aparecia sobre o menu, os tres icones nao
   respondiam ao ponteiro, e nao havia tooltip neles — o ponteiro estava
   pousando no campo de texto, nao nos botoes.
