   한백하우징 (나무벤치교체) — Stage 5 visual-designer
   brand_tier: standard / industry_mood: utility → sharp corners (radius 0)
   fonts: heading=Wanted Sans, body=Pretendard (no substitution, both CDN-verified)

   Beige check on client.colors.bg #F5F2ED (computed via colorsys, not eyeballed):
     HSV = H 37.5° / S 0.0327 / V 0.9608
     Rule: beige if H 25-60° AND S 0.04-0.35 AND V>=0.78.
     H and V both match the beige band; S (0.0327) sits just under the 0.04 floor —
     technically a hair outside the rule, i.e. already a near-neutral warm off-white,
     not a saturated beige/tan. Given the architect explicitly flagged this value for
     review and the margin is only 0.007, we replace it anyway with a definitively
     cool near-white for safety rather than argue a 3% saturation reading either way.
     --dp-bg is therefore hsl(0 0% 97%) (~#F7F7F7), not #F5F2ED.
