/* FCS Magazine — Archive (tag.hbs + author.hbs) styles.
 *
 * Spec: Doc #163 §2c (tag) + §2d (author).
 * Shared shell — both templates render the same .archive-item rows; only
 * the .archive-header treatment differs (tag → paper-deep + eyebrow,
 * author → paper-soft + avatar).
 *
 * Inheritance principles (Doc #163 §0):
 *   - Lift V7 tokens, fonts, eyebrow, .blog-all arrow vocabulary verbatim.
 *   - Chronological list, NOT card grid (Doc #163 §2c — archives need
 *     browsing, not curation; the homepage carries the grid vocabulary).
 *   - No reveal animations on list rows; static archives feel calmer
 *     without staged reveals.
 */

/* ─── 1. ARCHIVE HEADER ────────────────────────────────────
 * Tag header sits on paper-deep, author header on paper-soft. The eyebrow
 * partial fronts both. Title scale clamp(2.5rem, 5vw, 4rem) per Doc #163 §2c
 * — half a step below the page hero so a tag archive never competes with
 * a static page's masthead.
