   LOGO CENTERING FIX.

   The old rule was:
       .slot-row { display:grid; grid-template-columns:repeat(3,1fr); }
   Each of the Presenting / Lunch / Breakfast tiers holds exactly ONE
   logo slot, so that single slot landed in column 1 of 3 and sat hard
   left. `justify-content:center` could not fix it, because 1fr columns
   already consume the full width — there is nothing left to center.

   Flexbox is the fix: tracks are sized by content, so one, two, or
   three logos all center, and a partial last row centers too.

   animation and reveal everything on load.

   .reveal          fade + rise into place (default, most content)
   .reveal-fade     fade only, no vertical motion (logos, bands)
   .reveal-stagger  put on a GRID/ROW CONTAINER; its direct children
                    fade + rise together with a small staggered delay
