/* Tracktonica Library — camada de interface: admin (sistema e relatórios).
   As telas usam os componentes adm-* de assets/ui/admin.css (página, cabeçalho, seção,
   lista de configurações, tabela, pills). O wrapper é <div class="adm-page sys-page">;
   aqui ficam só complementos específicos, sempre escopados em .sys-page:

   .sys-facts / .sys-fact    números-resumo com rótulo em cima e nota embaixo
                             (.sys-fact-label, .sys-fact-value[.is-text], .sys-fact-note)
   .sys-switch               checkbox nativo como interruptor (dentro de .adm-row__control)
   .sys-unit                 unidade ao lado de um campo ("horas", "dias")
   .sys-form-foot            rodapé do formulário (botão salvar + dica)
   .sys-tag / .sys-tags      etiquetas neutras (permissões, tipo de download)
   .sys-cell-main/.sys-cell-sub  linha principal + linha secundária numa célula
   .sys-row-actions          botões de ação numa célula (alinhados à direita)
   .sys-table-foot/.sys-pager    paginação abaixo da tabela
   .sys-filters              barra de filtros em grade (.sys-filters-actions, label.is-wide)
   .sys-choice-grid/.sys-choice  grade de checkboxes com descrição
   .sys-list / .sys-item     lista de verificações (ícone de status + título + detalhe + pill)
   .sys-note                 aviso em linha (.is-ok .is-warn .is-error)
   .sys-secret               código copiável + botão "Copiar"
   .sys-meter / .sys-bar     barra de uso do disco / barra proporcional de ranking
   .sys-log / .sys-events    registro monoespaçado
   .sys-disclosure           <details> sem marcador nativo (chevron SVG)
   .sys-help                 dicas em colunas
   .sys-empty                estado vazio
   .sys-split                duas seções lado a lado
   Estados usam os mesmos nomes de adm-pill: is-ok | is-warn | is-error | is-info | is-accent.
