/* Wilhelm — The Ledger (research journal).

   Two themes. The site's dark brand world is the default everywhere; article
   pages open in LIGHT because sustained reading is easier on a light ground
   and because a page that looks like a printed document reads as more
   credible than one that looks like an app. The light theme is the brand
   inverted, not a new palette — parchment and ink already are the two brand
   colors, so nothing foreign gets introduced.

   Readers can flip it; the choice sticks in localStorage.

   Layout: the text column stays at a readable measure (~66 characters) at
   every width. On wide desktops the leftover space is filled with useful
   rails — contents on the left, a persistent join card on the right —
   rather than by stretching the prose, which would hurt it.

   The capture blocks reuse .optin-form / [data-capture] markup so
   /drink/optin.js wires them with zero changes. */
