/* First Camp Oven — one stylesheet, no framework, no web fonts, no JavaScript.
   Editing rules for future me:
   - Mobile first. Every @media block widens, never narrows.
   - System fonts only. A web font costs a round trip and we gain nothing.
   - Keep this file under ~400 lines. If it grows, something is wrong. */
