/* FCS Magazine — post.hbs (article reading view) styles.
 *
 * Spec: Doc #163 §2a (Step 4 of Doc #162 §7).
 * Sustained-reading typography. The most-visited template in any magazine
 * site, lowest tolerance for design self-indulgence — readers came for content.
 *
 * Inheritance principles (Doc #163 §0):
 *   - Lift V7 tokens, fonts, eyebrow, nav, footer verbatim (handled elsewhere).
 *   - Article body sits on plain --paper, NOT --paper-deep (paper-deep is the
 *     proof-spine register; reserved for the homepage hero).
 *   - No reveal animations on body content (staged reveals fight reading).
 *   - Featured image BELOW title block (NYT/Atlantic editorial pattern, not
 *     the homepage cover-spread pattern).
 *
 * Type scale references homepage Quote (clamp(2rem, 4vw, 3.75rem)) and
 * media-kit-title — pull-quote sits one half-step below those so each Zodiak
 * moment stays smaller than the next downstream Zodiak moment in hierarchy
 * (the masthead-Zodiak rule from Doc #158 §4).
 */
