/* The editorial and utility pages on the light interior design (Option F, approved 2026-09-10): the blog and its
   articles, field work and its case studies, privacy, terms, sign-in and 404.

   Loaded AFTER /light.css, which owns the theme tokens, the dark hero, the section furniture and the sheet
   (.s3 / .s3-row / .sol-k). Nothing in light.css is redefined here; everything new is namespaced `ed-`.

   Two ideas do the work:
   · long-form reading gets ONE centred column at a comfortable measure (~66-72 characters) — .ed-col + .ed-body;
   · anything structured — the article index, the imprint, the chain a case study was built from — keeps the
     house sheet discipline: a label column and a content column, every label at the same x as on an
     industry page (170px, 200px past 1200px). */

/* ---------- the dark hero with no picture ------------------------------
   The blog, field work, privacy, terms, sign-in and 404 have no picture of their own, and one must not be
   invented for them. They get the same dark ground, sized to the words rather than to a photograph. */
