 * Scoped via body.wuc-flagship-osi (added by functions-blog-osi.php body_class filter)
 *
 * Version: 1.0.7  (2026-05-11) — v1.0.7 fixes mobile/tablet rendering.
 *                                Two issues found via Chrome DOM probe at 375px sim:
 *                                  (1) .article-layout grid items missing min-width:0
 *                                      — min-content propagation from the in-body
 *                                      comparison table forced .article-body to render
 *                                      at 440px inside a 307px container (99px overflow
 *                                      cascading to every paragraph, heading, figure,
 *                                      callout). Fix: min-width:0 on .article-toc and
 *                                      .article-body (the grid items). Standard CSS
 *                                      Grid trap: 1fr === minmax(auto, 1fr) by default,
 *                                      and auto = min-content.
 *                                  (2) 12-column comparison table inside .article-body
 *                                      had unbreakable header phrases summing to 436px
 *                                      min-content. At any narrow viewport the table
 *                                      busts the column even after fix (1). Fix: tables
 *                                      become display:block + overflow-x:auto so they
 *                                      scroll horizontally inside the column without
 *                                      breaking page layout.
 *                                v1.0.6 adds .audio-overview block styling
 *                                for the 21:07 audio companion player. Dark navy
 *                                gradient frame to differentiate from text content.
 *                                v1.0.5 added 3 new figures + figure breakout CSS.
 *                                v1.0.4 added Epic EHR context to L7 callout.
 *                                v1.0.3 added kses form/input/button allow-list.
 *                                v1.0.2 added:
 *                                  * Lead-magnet text visibility (specificity bump)
 *                                  * Form submission UI states (loading / success / error)
 *                                v1.0.1 added figure SVG sizing (preserved).
 * Splice: template-edit (CSS only — no opcache wait, no service restart)
 * Owner/mode: daemon:daemon 644

/* === v1.0.7 — Mobile/tablet rendering fixes ================================
   Fix #1: CSS Grid track min-content trap.
   .article-layout collapses to grid-template-columns: 1fr at <1024px. By default
   1fr means minmax(auto, 1fr) and auto = min-content. The wide 12-column table
   inside .article-body has min-content of 436px, which forced the grid track to
   436-440px wide even when the container was only 307px (mobile). Result: 99px
   horizontal overflow cascading to every descendant.
   Solution: explicit min-width:0 on the grid items breaks the min-content chain
   so the track honors the parent's available width. Safe at all viewports —
   the desktop two-column rule already uses minmax(0, 1fr) for the body track. */
