+## PHASE 50 — Branding "B2BCall by Handix" (pedido do usuário: logos novos)
+- [x] Usuário forneceu 3 logos novos na raiz do projeto (`logo_b2bcall_
+      horizontal.png`, `logo_b2bcall_quadrado.png`, `Logo_Handix.png`,
+      empresa mãe). Processados com `sharp` (trim de whitespace + resize
+      pra tamanho web) e salvos em `apps/frontend/public/branding/` como
+      `b2bcall-horizontal.png`/`b2bcall-quadrado.png`/`handix-logo.png` —
+      o antigo `b2blogo.png` foi substituído (era o mesmo desenho, só com
+      mais espaço em branco ao redor)
+- [x] achado ao processar: `Logo_Handix.png` original era RGB (sem canal
+      alpha) — fundo branco opaco, não transparente. Aplicado
+      `brightness-0 invert` nele (mesmo filtro já usado no logo B2BCall
+      pro painel escuro do login) virava um retângulo branco sólido, sem
+      nada visível dentro. Corrigido com um script Node usando `sharp`
+      pra recolorir pixels próximos de branco (limiar 245) como
+      transparentes antes de salvar — resultado com alpha real,
+      confirmado lendo os bytes RGBA de um pixel de fundo (0,0,0,0)
+- [x] Sidebar (tenant e platform): ícone quadrado do B2BCall ao lado do
+      nome do tenant/"PLATFORM" no cabeçalho (canto superior esquerdo da
+      tela) — some junto com o texto quando a sidebar está recolhida,
+      mesmo comportamento de antes
+- [x] Topbar: logo da Handix (canto superior direito, com link pra
+      www.handix.com.br em nova aba) antes do seletor de tema — escondido
+      abaixo de `sm` (mobile) pra não espremer a topbar já apertada
+- [x] Login: "BY HANDIX" abaixo do logo principal do B2BCall no painel de
+      marca, e um rodapé com o logo da Handix (versão branca) + link pra
+      www.handix.com.br
+- [x] Testado ponta a ponta via Puppeteer: tela de login, dashboard do
+      tenant e da plataforma (claro e escuro), sidebar recolhida, drawer
+      mobile — logos aparecendo corretos em todos, sem o artefato de
+      retângulo branco no Handix

           STORY: a platform admin opens the dashboard and reads the whole platform's live state — tenants, calls in flight, capacity headroom — in one glance.
           FIRST VIEWPORT: sidebar+topbar shell, content opens on a grid of large mono instrument tiles for live counters, live ones pulse; a quieter row below for not-yet-available billing figures, explicitly marked pending.
           FORM: concept-seed surface/operate key ae95b901, candidate #3 (seven-segment/instrument panel) chosen over dealt lead #4 (HyperCard) — reasoned override, no interactive decision round available in this environment, disclosed to the user.
