A simple Halloween door sign on a pure flat white background, landscape, in clean flat illustrated shapes with a very fine paper grain. Three lines of hand-lettered text stacked and left-aligned, reading exactly: "second" / "bathroom" / "upstairs". All lowercase, no other words anywhere. The lettering is a witch's dip-pen script made very large and very bold: thin upstrokes and heavy downstrokes, slanted about 15 degrees to the right, every ascender and capital topped with a single sharp point leaning right like a witch's hat tip, baseline strokes ending in small tight curls, letters mostly unjoined and hopping slightly up and down along the baseline, open counters, fully readable from several steps away. The letters are solid deep indigo-purple (#2E1A55) with a thick pumpkin-orange (#FF7A1A) offset shadow to the lower right for contrast against the white. The three lines fill about 62% of the canvas width and most of the height, with generous white margin all around. On the right side, a large flat-illustrated skeleton hand and forearm in bone white with deep indigo outlines and soft grey-lilac shading comes in from the right edge. The index finger is extended and points to the right, the other fingers curled, with clear knuckle and finger-bone shapes. The hand sits at about 28% of the canvas width, vertically centred beside the text. It is an unambiguous, bold pointing arrow. Small accents only in the corners: one tiny flat pumpkin-orange jack-o-lantern with a glowing face at the lower left, two small indigo bats at the upper left and upper right, and one small slime-green (#7ED321) spider dot. Everything stays clear of the words, with nothing busy behind the lettering. Mood: playful-spooky and friendly, not frightening, no blood. Keep all text and key elements inside a safe margin of 6% from every edge.
