   iTracker — Spacing & radius tokens
   ★ 本檔即 token 值正本，直接改這裡。站台載入 Pages/Shared/_DesignTokens.cshtml（一律在 site.css 之前）。

   Spacing: strict 4px base grid (Linear). --space-0_5 = 2px is the
   ONLY exception (badge/chip inner padding, thin indicator bars).
   1px hairlines and >40px layout gaps live outside this system.
   Spacing tokens never switch with theme.
   Radii: Linear-aligned even ladder 4/6/8/12. Nested corners stay
   concentric: inner radius < outer radius.
