/* Kenspeck — "The Interlinear" visual direction (design_handoff_interlinear).
   The game is set like a bilingual dictionary: interlinear gloss pairs with the
   foreign original redacted during play, rubricated sense numbers, a blue gloss
   rule as the only structural accent. Palette and scale come from the handoff's
   token table; dark mode derives per its notes (contained sheet on a near-black
   ground). */
