/**
 * LTC Insights Article — editorial single-post template (2026-08-09).
 *
 * Only enqueued on "post" post type singles — see
 * ltc_child_enqueue_insights_styles() in functions.php. Reuses
 * .ltc-card-insight / .ltc-insight-grid (ltc-home.css, loaded
 * site-wide) for the related-articles strip rather than redefining a
 * card component; everything else here is specific to the article
 * hero, reading column, table of contents and closing continuation
 * area, so it lives in its own file per this theme's existing
 * one-file-per-page-type convention (ltc-contact.css,
 * ltc-programmes.css, ltc-resource-detail.css).
