wuwiandClaude Opus 5 4a034773aa Draw the tutorial properly, and put the logo and gore on the menu
The tutorial was borrowing a court tile, the in-game how-to icon and a weapon
icon, none of which were drawn to be looked at. Four purpose-made 2:1 panels
now: the serve with a tapping hand, the slingshot pull with chevrons into a
zombie, the weapon rack, and the floodlit duel. They get the full card width
above Marvin instead of being squeezed into the text column beside him.

The menu wears the title logo instead of a Silkscreen headline, and the two
buttons wear generated plates — START GAME bloodied, TUTORIAL nearly clean.
The lettering stays Silkscreen on top: generated type is a lottery and would
not match the rest of the HUD.

Two things the art needed. Quantise the panels at 128 colours, not 64 — big
flat fields with saturated accents is where a small palette shows, and 64
turned the tennis ball beige. And find a plate by its BRIGHT BORDER, never by
the corner colour: one plate came back on a near-black margin, the other on a
transparency checkerboard that differs from itself everywhere and matched the
whole canvas.
