/*
 * GFS Single-post layout — Sprint 8 Phase 2
 * Loaded only on single posts that have _gfs_post_variant meta set.
 * Builds on gfs-kit-v2.css typography + patterns. Adds variant-specific
 * layout (article / howto / chapter / ticker / course).
 *
 * Class scoping: every selector lives under .gfs-post or .gfs-post--{variant}
 * so it can't bleed into other post types or homepage rendering.
