One look for Subi AI

Every place Subi AI shows up in the merchant admin now uses the same accent color and mark, instead of the mix of styles that had grown up around each feature separately.
The Subi AI star and its disc, the AI component on Home and its banner, the Best fit badges that recommend a feature, suggested questions, links inside AI answers, and the New features modal all draw from the same palette now. The onboarding wizard's goal step, which already used the assistant, picks up the same colors too.
This is a visual consistency change: it doesn't add a new AI capability or change what Subi AI can answer. The New features modal also changes shape alongside the color update, showing one scrolling row of cards instead of a single large hero plus small tiles, with artwork chosen so no two cards in the same batch repeat the same picture.
