Subject: [PATCH] style: unify lightbox CSS, adapt entry-cover and post-card
 blur

remove the duplicated .image-viewer-* and .md-image-lightbox-* rules
(~93 lines); add a single .lightbox-* set sized/positioned by JS
transform. entry-cover and post-card-cover now target the blur-img
structure (4:3 ratio on cards, cover-fill on entry cover).
