/* =====================================================================
   links.lightly-salted.com — the linktree layer only.

   site.css (shared design system) and hub.css (dashofblum's lab-notebook
   skin) do the heavy lifting: palette, mono type, the dot-grid paper and
   the `//` kickers. This file adds only the two things the hub has no
   vocabulary for — the circular portrait and the icon-button grid — and
   it builds both entirely out of hub tokens so the rust accent stays the
   single source of truth.

   Rule inherited from hub.css: DON'T hardcode the accent. Every colour below
   is a var() off the hub. Changing --accent in hub.css restyles this page too
   (darkroom mode included).

   Nothing here overrides site.css layout primitives (.container, .section,
   .page-hero, .kicker, .lede) — those are used as-is.
