/* Sekolah Mazmur 21 - redesign v2
   Direction: type-led editorial. No photographic filler; the only real image
   available is the school's own YouTube thumbnail, used once as the hero asset.
   Palette: bone paper + ink + ONE accent (deep green). Locked page-wide.
   Radius system: blocks 20px, buttons pill, inputs 10px. No exceptions. */
