+# Sistema de Ícones — CyberCore Signer
+
+Este documento estabelece as especificações de design, gramática visual, convenções de código e diretrizes de renderização do sistema de ícones do **CyberCore Signer**.
+
+---
+
+## 1. Gramática Visual e Grid Base
+
+O sistema de ícones do CyberCore Signer foi projetado para oferecer clareza, consistência corporativa e alta fidelidade tanto no **Modo Claro** quanto no **Modo Escuro**, além de suporte a telas com alta densidade de pixels (HiDPI / Retina).
+
+| Parâmetro | Especificação | Descrição |
+| :--- | :--- | :--- |
+| **ViewBox Canônico** | `0 0 24 24` | Todos os ícones são desenhados em um canvas quadrado padronizado de 24×24 pixels. |
+| **Safe Area** | `2px` em todas as bordas | Os grafismos principais ficam contidos na área útil de `20×20px` (coordenadas de `2` a `22`). |
+| **Stroke (Espessura)** | `1.75px` a `2.0px` | Traços consistentes entre todos os glifos vetoriais, proporcionando peso uniforme. |
+| **Cantos e Terminações** | `round` | `stroke-linecap="round"` e `stroke-linejoin="round"` para um visual moderno e suave. |
+| **Texto Embutido** | **Nenhum** (`Proibido`) | Ícones não devem incorporar elementos `<text>`. Toda semântica é transmitida por formas puras e labels da interface. |
+
+---
+
+## 2. Paleta de Cores e Tintas Semânticas
+
+Os ícones utilizam `currentColor` como tinta principal, permitindo repintura dinâmica e herança das cores dos tokens do tema ativo:
+
+| Papel | Token / Cor Modo Claro | Token / Cor Modo Escuro | Uso |
+| :--- | :--- | :--- | :--- |
+| **Tinta Principal (`currentColor`)** | `#1E293B` (`-fx-color-text`) | `#F1F5F9` (`-fx-color-text`) | Linhas de contorno, silhuetas e glifos primários. |
+| **Acento Primário** | `#0288D1` (`-fx-color-primary`) | `#38BDF8` (`-fx-color-primary`) | Elementos de destaque, dobras de documentos, escudos. |
+| **Sucesso** | `#10B981` (`-fx-color-success`) | `#34D399` (`-fx-color-success`) | Confirmações, validações concluídas (`check`, `validate`). |
+| **Alerta / Atenção** | `#F59E0B` (`-fx-color-warning`) | `#FBBF24` (`-fx-color-warning`) | Avisos de validade próxima, selos e certificações (`seal`). |
+| **Erro / Perigo** | `#EF4444` (`-fx-color-error`) | `#F87171` (`-fx-color-error`) | Ações destrutivas, falhas de assinatura (`error`, `exit`). |
+| **Atenuado / Muted** | `#64748B` (`-fx-color-text-muted`) | `#94A3B8` (`-fx-color-text-muted`) | Guias internas, linhas secundárias, fechar (`close`). |
+
+---
+
+## 3. Escala de Tamanhos Padronizados
+
+Para manter a consistência da interface, os ícones devem ser consumidos exclusivamente através dos 5 tamanhos canônicos definidos na fachada `Icons`:
+
+```
+   16px         20px         24px         32px         40px
+ [ Micro ]    [ Pequeno ]  [ Padrão ]   [ Médio ]    [ Grande ]
+```
+
+- **`SIZE_16` (16×16 px):** Badges de status de certificado, botões auxiliares pequenos de janelas de diálogo (ex.: fechar, atualizar).
+- **`SIZE_20` (20×20 px):** Menus secundários, botões de ação secundária, itens compactos em listas.
+- **`SIZE_24` (24×24 px):** Tamanho padrão de componentes, botões de barra lateral do Hub, campos com ícone prefixado.
+- **`SIZE_32` (32×32 px):** Cabeçalhos de diálogos de aprovação CCSP, títulos de assistentes.
+- **`SIZE_40` (40×40 px):** Cartões e botões do painel principal (Hub de Ações Rápidas).

+## 5. Implementação Técnica
+
+### Fachada `Icons`
+A classe `br.com.cybercore.signer.ui.components.Icons` centraliza a instanciação:
+```java
+// Tamanho padrão (24px) com cor do tema ativo:
+Node icon = Icons.settings();
+
+// Tamanho específico:
+Node refresh = Icons.refresh(Icons.SIZE_16);
+
+// Tinta customizada:
+Node custom = Icons.of("pdf", Icons.SIZE_40, Color.web("#0288D1"));
+```
+
+### Repintura Dinâmica
+Ao registrar alteração de tema em `ThemeManager`, os nós de ícone baseados em `currentColor` recebem automaticamente o listener e atualizam suas cores em tempo real sem necessidade de recriar a janela.

+# UI Troubleshooting & Resolução de Estilos (JavaFX CSS)
+
+Este documento registra a investigação da causa raiz de problemas visuais na interface gráfica do CyberCore Signer, em especial a falha de renderização de textos com cor preta (`Color.BLACK`) via `setStyle()`, a eliminação definitiva de estilos inline de cor e a transição para o tema claro unificado.
+
+---
+
+## 1. O Problema: Texto Renderizado em Preto (`#000000`) via `setStyle`
+
+### Sintoma
+Em diálogos modais como `ExitConfirmationDialog`, `PdfSignDialog` e `PdfCertificateSignDialog`, chamadas como:
+```java
+subtitle.setStyle("-fx-text-fill: -fx-text-secondary;");
+lblDocName.setStyle("-fx-text-fill: -fx-text-primary;");
+dragTip.setStyle("-fx-text-fill: -fx-text-secondary;");
+```
+resultavam em texto renderizado com a cor preta opaca (`#000000`), mesmo quando o token `-fx-text-secondary` já se encontrava definido no arquivo `theme.css`.
+
+---
+
+## 2. Investigação Técnica e Causa Raiz
+
+### 2.1 Por que `setStyle("-fx-text-fill: -fx-text-secondary")` renderiza PRETO?
+No motor de estilização do JavaFX (`com.sun.javafx.css.StyleManager` / `CssStyleHelper`):
+
+1. **Momento da Avaliação (Timing) de Nós Fora da Árvore da Scene:**
+   Quando um nó (como um `Label` ou `Text`) é instanciado no código Java dentro do construtor de um diálogo e recebe `.setStyle("-fx-text-fill: -fx-text-secondary;")`, ele ainda **não foi anexado ao grafo de cena** (`Scene`).
+2. **Escopo de Resolução de Lookups Ausente:**
+   Como `-fx-text-secondary` é uma cor pesquisada (*looked-up color*) definida no seletor `.root` da folha de estilo da aplicação, a engine de CSS do JavaFX tenta resolver essa variável subindo a cadeia de nós pais (`parent chain`) até alcançar `.root`. Como o nó está solto na memória (sem parent e sem Scene vinculada no instante da chamada), o lookup não encontra nenhuma definição válida.
+3. **Mecanismo de Fallback Silencioso do Modena (`Color.BLACK`):**
+   O analisador do JavaFX não lança exceção ao falhar na resolução de uma cor de lookup em estilo inline. Em vez disso, seu conversor (`PaintConverter` / `ColorConverter`) assume o valor padrão de salvaguarda da especificação Modena: **`Color.BLACK` (`rgba(0, 0, 0, 1.0)`)**.
+4. **Imutabilidade e Prioridade do Estilo Inline:**
+   O estilo inline atribuído via `setStyle(...)` possui a especificidade mais alta na hierarquia CSS do JavaFX. O valor pré-resolvido como `Color.BLACK` fica gravado diretamente no cache de estilo do nó. Quando a Scene finalmente executa a passagem formal de CSS (`applyCss()` / `layout()`), a engine prioriza o estilo inline e não reavalia o lookup que falhou previamente.
+
+### 2.2 Por que o problema não ocorre com Classes CSS?
+Quando utilizamos classes semânticas declaradas em folha de estilo (ex.: `lbl.getStyleClass().add("text-muted");`):
+```css
+.text-muted {
+    -fx-text-fill: -fx-text-secondary;
+}
+```
+A resolução da regra é postergada até que o nó pertença à hierarquia da Scene e a passagem de CSS do JavaFX seja executada. Nesse momento, o nó tem acesso direto às definições de `.root`, resolvendo perfeitamente o token para a cor correta da paleta (`#475569`).
+
+---
+
+## 3. Diretriz Arquitetural: Proibição de Cores em `setStyle()`
+
+Fica estabelecido como regra obrigatória de desenvolvimento no `cybercore-ui`:
+

+## 4. Salvaguardas Automatizadas
+
+O teste de arquitetura [`DesignTokenGuardrailTest.java`](file:///var/www/cybercore/cybercore-signer/modules/cybercore-ui/src/test/java/br/com/cybercore/signer/ui/theme/DesignTokenGuardrailTest.java) atua como barreira de compilação contínua:
+- Varre todos os arquivos `.java` no módulo `cybercore-ui` e reprova automaticamente o build se qualquer chamada `setStyle()` contiver propriedades ou valores de cor.
+- Valida matematicamente a relação de contraste WCAG AA (mínimo de 4.5:1 para texto normal) em todas as combinações de tokens de texto sobre superfície/fundo.
+- Assegura ausência de seletores ou classes residuais de temas escuros (`.theme-dark`, `AppTheme`, `isDark()`).

+## 5. Comportamento da Barra de Título Nativa no Windows (DWM em Modo Escuro)
+
+### Diagnóstico Operacional
+Quando o sistema operacional Windows 10/11 está configurado no "Modo Escuro do Sistema" (*Personalização > Cores > Escolher o modo: Escuro*), o gerenciador de janelas do sistema operacional (**Desktop Window Manager — DWM**) aplica automaticamente o atributo `DWMWA_USE_IMMERSIVE_DARK_MODE` na moldura não-cliente da janela nativa (`HWND`).
+
+Como o CyberCore Signer utiliza decoração nativa padrão (`StageStyle.DECORATED`) para preservar o comportamento esperado pelo usuário empresarial — incluindo cantos arredondados, atalhos de teclado nativos, suporte a múltiplos monitores com DPIs distintos e os *Snap Layouts* do Windows 11 — a barra de título nativa é desenhada pelo Windows em tom escuro, enquanto o conteúdo da janela exibe o tema claro unificado da aplicação.
+
+### Diretriz de Arquitetura (Não Forçar)
+Em estrita conformidade com as diretrizes do projeto (Regras 2 e 23):
+1. **Não forçar a barra de título:** Evita-se o uso de hacks de baixo nível via JNA/JNI para sobrescrever o DWM do Windows ou janelas não decoradas (`UNDECORATED`), o que causaria quebra de acessibilidade e perda de recursos nativos do sistema.
+2. **Harmonia Visual:** A moldura do Windows atua como moldura de sistema e o conteúdo claro do CyberCore Signer permanece legível, íntegro e em total conformidade com a especificação de interface.
