IPTVnator Theme Style

Canonical Sources

• Theme contexts and app tokens: apps/web/src/m3-theme.scss
• Shared forwarding inventory: libs/ui/styles/_index.scss
• Shared partials: libs/ui/styles/_portal-layout.scss, libs/ui/styles/_content-grid.scss, libs/ui/styles/_portal-sidebar.scss, libs/ui/styles/_panel-header.scss, libs/ui/styles/_detail-view.scss, and libs/ui/styles/_detail-view-actions.scss
• UI policy and migration debt: docs/architecture/iptvnator-ui-guidelines.md

The index is a barrel, not a configured Sass include path. Production consumers currently use relative @use paths to the needed partial.

Token Boundary

• App-owned surfaces, text, separators, hover states, selections, and provider accents use --app-* tokens from m3-theme.scss.
• Use --app-selection-on-color for foregrounds placed on the selection accent; do not assume white has enough contrast in both themes.
• Angular Material mixins and Material-component overrides may use Material tokens. Outside Material-owned components, use a --mat-sys-* token only after proving it is emitted in both light and dark contexts and supplying a real app-token or literal fallback.
• Local semantic status colors are acceptable. Existing hard-coded layout, selection, and EPG surface colors are migration debt, not precedent.

Shared Layout Rules

• Extend the matching partial instead of copying a large provider stylesheet. Provider-neutral services and UI use the existing shared data-access/UI libraries; repeated visual structure belongs in a shared Sass partial. Portal-shared consumers use their existing forwarding style modules instead of copied SCSS.
• In an Electron drag region, every interactive descendant—buttons, links, inputs, overlays, and resize handles—must explicitly use app-region: no-drag. The shared directive-generated .resize-handle does not set this centrally yet; consumers in drag regions must cover it themselves and must not assume the generated handle opts out.
• A shared change must be checked across M3U, Xtream, Stalker, workspace, portal catalog/shared UI, and unified collections where relevant.

Validation

Run the affected consumer's Nx lint/test/build target. Inspect light and dark themes, selected/hover states, and Electron title-bar drag/no-drag behavior.
