/* What's For Dinner Tonight — warm, readable, fast.
 *
 * Single stylesheet for the whole site. No build step beyond build.py
 * copying this file into ./build/.
 *
 * Design notes:
 * - System fonts so the site feels native on each platform
 * - Comfortable measure (45-75 chars per line) for actual reading
 * - One column, generous spacing, no sidebar, no popups
 * - Color-as-wayfinding palette mirrors the iOS app:
 *     coral  = primary brand / Eat In path
 *     sage   = pantry / "What do I have" path
 *     navy   = Eat Out / restaurant path
 * - No JS required
