+All four files render as one page at `/portfolio/`. You can mix `.md`, `.html`, and `.php` freely — use whichever format fits each section best.
 
-**Use case:** Build pages from modular components—header, content, footer, etc.
+**Why number prefixes?** Files are sorted using natural sort (`strnatcmp`), so `10-` comes before `20-` comes before `30-`. Using increments of 10 leaves room to insert new sections later without renaming existing files. Files without a number prefix sort after numbered files.
