Add overflow-hidden to SkillPageLayout and min-w-0 to flex children to ensure wide content (like SQLite tables with many columns) scrolls internally rather than causing the entire page to scroll horizontally.
Rename components and reorganize directory structure: - skill-doc-editor.tsx → file-content-panel.tsx (handles edit/preview/download) - editor-area.tsx → content-area.tsx - editor-body.tsx → content-body.tsx - editor-tabs.tsx → file-tabs.tsx - editor-tab-item.tsx → file-tab-item.tsx Create viewer/ directory for non-editor components: - Move media-file-preview.tsx from editor/ to viewer/ - Move unsupported-file-download.tsx from editor/ to viewer/ This clarifies the distinction between: - editor/: actual file editors (code, markdown) - viewer/: preview and download components (media, unsupported files)
