/* Category and brand archive intro - the section board.
 * See functions/sd-category-intro.php for the shape and the reasoning.
 *
 * The block gets the whole 1,680px of .catalog_top and is built as the opening
 * spread of a catalogue section: a reading rail across the top, then the section
 * heading and its standfirst side by side. Boldness is spent in one place - the
 * red tick that starts the rail - and the rest is hairlines and type.
 *
 * Colours are the house tokens the home page and the clearance archive already
 * use, so this belongs to the same site. The accent is the brand red, not the
 * AIMS green the first version borrowed: red is what the header, the search
 * button and the deals nav all use, and green on this store means AIMS.
 *
 * SPECIFICITY. The theme prints an inline <style> carrying
 * `h2, .woocommerce h2, .woocommerce-page h2 { font-size: 44.425px }` - 0,1,1,
 * which beats a lone `.sd-cat-intro__heading`. Anything the theme also styles by
 * element is written here as `.sd-cat-intro .sd-cat-intro__x` to get above it. */
