Ribbon
An Office-style single-line Ribbon (Word Online's “Faixa de Opções de Linha Única”), composed from the kit Tabs, Toolbar, and the headless Overflow priority system. Every command renders as an icon in the bar and as an icon + label row inside the “…” overflow menu.
Light
Open the far-right display-options chevron (Word's RibbonLayoutSwitcher) to switch Clássica ↔ Linha Única on the same tabs — the active tab is preserved. In single-line, Desfazer is pinned and commands drop by priority into the “…” menu as the row shrinks. In classic, shrink the band and whole groups collapse to a dropdown button — Parágrafo (collapsePriority 50) before Fonte (40); open a collapsed group to use its commands in a flyout. Toggle Mostrar apenas as guias for tabs-only mode.
