CAMPFIRE Style Design System (DESIGN.md, Japanese UI)

Design approach: A clean, white-based layout composed of brand red #ef4846 accents (flame icon, progress bars) and dark text #4d4a4a. Information is consolidated into a grid of project cards, enabling a browsing-focused UI where thumbnails, achievement rates, and funding amounts can be compared at a glance - Density: A card-list style with high information density. Project cards pack details into small text (12px), and body line-height is 1.4 — tight by Western typography standards. Headings also use 1.4–1.5, trimming away whitespace - Keywords: White-based, information density, card grid, bra
