+## Competition editions
+
+The homepage is the current 2026 competition. Past editions live at
+`/competitions/2024/` and `/competitions/2025/`; organization content lives at
+`/about/`. Competition-specific sponsors, photos, and results are assigned in
+`src/data/competitions.ts`, with shared logo definitions in `src/data/sponsors.ts`.
+Archives only display available historical content, never current registration
+information. New editions need a static HTML entry, Vite input, sitemap entry,
+and Lighthouse URL in addition to their competition data.
