   スタンドコービー (STAND COBE) - standing sake bar, Kitanagasa-dori
   VARIANCE 7 / MOTION 3 / DENSITY 4

   PALETTE RATIONALE. The verified identity is a stylish standing
   SAKE bar (review tags: 立ち飲み屋 9, 日本酒 7, 焼売 5, 焼酎 3 —
   beer appears nowhere, whatever the prospect list said). So the
   iconography is sake, not taps: unbleached kinari cloth as the
   ground and one aizome (indigo-dye) accent, the noren palette.
   Ground #efe8d8 is deliberately warmer and darker than 11-mykonos'
   limestone #f4f2ed, and the accent #21374e is a deep iron navy,
   far darker than 11's Aegean #1f5f8b, so neither axis pairs with
   any existing site.

   TYPE. Display Kaisei Tokumin (700/800 verified on the Fonts API),
   a sturdy text-mincho that reads "good sake" without costume.
   Body Kaisei HarunoUmi (400/500/700 verified; de-duped 2026-09-13): its soft literary strokes
   carry the pay-as-you-go casualness of a tachinomi against the
   formal display face. Radius 9px.

   Accent-as-surface takes white ink; accent-as-text is dark enough
   to pass on kinari directly (computed 9.0:1).
