/* Tiller — shared styles. One file, no build step, no webfonts.
   Palette: warm paper. Chosen deliberately — the freight software category is
   saturated in corporate blue, and warm paper reads calm rather than corporate.
   (No Google Fonts on purpose: a product that promises "your data is yours" shouldn't
   phone a third party on every page load. The system stack is fast and honest.) */
