   TinySpacer — assets/css/components.css
   -----------------------------------------------------------------------------
   Reusable UI component library. Builds on the design tokens defined in
   assets/css/global.css — load global.css FIRST so every --ts-* variable is
   available here.

   Scope note (intentional, to avoid regenerating existing code):
     • Buttons  -> already defined in global.css (.ts-btn, .ts-btn--secondary).
                   Reused as-is; NOT redefined here.
     • Badge/Tag -> base .ts-badge / .ts-tag live in global.css. This file adds
                   only NEW, non-colliding modifiers (.ts-badge--outline, etc.).
     • Cards    -> base .ts-card lives in global.css. The component cards below
                   (category / article / newsletter) are NEW, distinctly-named
                   classes so there is zero selector collision.

   Enqueue (add to tinyspacer_enqueue_assets() in functions.php):
     wp_enqueue_style(
       'tinyspacer-components',
       get_theme_file_uri( 'assets/css/components.css' ),
       array( 'tinyspacer-global' ),
       filemtime( get_theme_file_path( 'assets/css/components.css' ) )
     );

   Mobile-first: base rules target small screens; wider layouts are layered on
   at min-width breakpoints. No JavaScript required by any component.
