/* Certifications — full rebuild (explicit direction: the previous pass's
   two cards were much too wide, the badges too small, and a redundant
   "Voir la certification" line duplicated what the whole card already
   does). Small, near-square, fully-clickable cards, using the exact same
   dark-glass card recipe (--li-* tokens, declared in skills-hero.css) as
   every other card family across the redesigned pages.

   Plain "Certifications" title above them (explicit direction — the
   earlier heading + subtitle was removed, then a bare title asked back
   "comme arbre de compétences": same .skills-section-heading class as
   the tree's own H2, no subtitle, no extra wrapper class of its own).
   The two cards simply center themselves in the row at every width. */
