/* Goatface Tech — blog shelf styles.
   Shared by /blog/ (index) and each post; layout mirrors the main site.

   READABILITY STANDARD (2026-07-19, standing standard for all Goatface properties):
   the blog is where people READ, so it must be the most legible surface we own. Dark
   theme stays, but TEXT is not grey — body copy is near-white (--ink), essay body is
   18px / 1.75, and the small letterspaced labels are sized up + high-contrast. Every
   text element must clear WCAG AA (4.5:1) on the near-black background. The muted greys
   (--dim) are for hairlines/borders ONLY — never for text. See DESIGN.md. */
