/* ============================================================
   YC Luckystar — style.css (v7 redesign)
   Palette: midnight navy + sail cyan (from the YC Luckystar
   sail logo). Light cool-gray sections alternate with deep
   navy bands. Fonts: Manrope (headings) + Inter (body) +
   JetBrains Mono (part numbers).
   Legacy variable aliases (--green-*, --gold, --cream) are kept
   so the catalog pages under parts/ pick up the new theme
   automatically.
