   Univik Blog GUIDE layout  -  /assets/css/blog-guide.css
   Load after blog.css. Adds a full-width article grid with a measured reading
   column and "wide" breakouts for 1200x900 screenshots, an inline TOC,
   step headings, framed screenshots with zoom and a related-posts row.

/* Article grid: three named tracks.  full | wide (1220) | prose (740) | wide | full
   Every direct child sits in the prose column by default (~76 characters per line).
   Add class "wide" to a figure, table, card row or CTA to span 1220px.
   Add class "full" for a viewport-wide band. Side tracks collapse to 0 on
   narrow screens so the same markup works on mobile with no extra rules. */

/* ==================== CSS MOCK SCREENS ====================
   Hand-built UI screens that sit inside .shot-frame instead of an <img>.
   The .mock box is a 4:3 container; every size inside uses cqw units, so a
   layout designed at 1200x900 scales with the column and stays sharp at any
   width. Decorative recreations of vendor screens, never real data.
   Mark each with role="img" and an aria-label that says what it shows. */
