+### Task Progress
+
+| Task | Status | Notes |
+| --- | --- | --- |
+| `P1.1` | Completed | Semantic token layer landed in `wwwroot/app.css` with compatibility aliases to keep existing pages stable. |
+| `P1.2` | Pending | Typography update will change font loading and global font tokens. |
+| `P1.3` | Pending | Theme modes will be introduced after typography is stable. |
+| `P1.4` | Pending | Theme persistence depends on the theme state service. |
+| `P1.5` | Pending | Shell replacement follows once tokens and theme plumbing exist. |
+| `P1.6` | Pending | Shell slots and nav utilities depend on the new shell. |
+| `P1.7` | Pending | Skip link and landmark work will land with the shell markup. |
+| `P1.8` | Pending | Tools-specific shell emphasis is final Phase 1 polish. |

 ### Goal
 
 Establish the shared shell, tokens, typography, and theme system that every destination will inherit.
