   PURPOSE:  The whole site's styling. One file, cached at the edge, no imports,
             no webfonts.
   VERSION:  0.3.0
   DATE:     2026-08-16
   CHANGELOG
   0.1.0  2026-08-16  Extracted from the single-page build.
   0.2.0  2026-08-16  Multi-page: nav, home, part pages, footer.
   0.3.0  2026-08-16  New identity. The previous palette - cool neutrals, one
                      teal-blue accent, mono labels - read as a cousin of the
                      other projects, which cluster on near-black grounds with a
                      single bright accent (mint, lime, yellow, amber) or warm
                      cream with tan. Nothing in the estate used red as a
                      PRIMARY, and nothing used a printed look.

                      So: a parts catalogue. Paper ground, oxide red masthead,
                      part numbers set as black stamps, flat square chips, heavy
                      rules. Red carries the engine side, cobalt the body side -
                      a two-colour print, which is what an interchange manual
                      actually was. No gradients, no glow, no rounded cards. */
