/* --- TITLE TEXT SHADOWS ------------------------------------------------
   Two strengths, defined once so every title across the site is consistent
   and tunable from one place:

   --image-title-shadow  text sitting directly ON a photo (carousel copy,
                         catalogue tile labels). Heavy, because the backdrop
                         underneath can be any brightness.
   --panel-title-shadow  headings on a glass panel (news, blog, product page,
                         section headings). Light — enough to lift the text
                         off the surface without smudging it.

   --tile-caption-shadow  the catalogue tile captions specifically. Same as
                          the image shadow while the text is white; inverted
                          to a white halo in the light theme, where those
                          captions turn dark and a dark shadow would read as
                          a smudge rather than depth.

   In the light theme the panel shadow also drops to a whisper. The carousel
   keeps the full image shadow in both themes — its copy stays white over a
   photograph, so the shadow there is legibility, not decoration.
