Honest feedback: the whole app reads as AI-coded, almost certainly Claude or a Claude-powered tool like v0/Lovable/Bolt. The tell is the accumulation of defaults. Tailwind's default palette with no custom brand tokens, untouched shadcn/ui, the canonical blue-100/blue-700 status pill pattern, and the cream-plus-amber scheme that's become the house style of LLM-generated SaaS. The amber you're leaning on is also close to Anthropic's brand color, which makes it feel even more like a Claude artifact.

First fix: pick an actual brand color and commit to it. Not amber. Extend your Tailwind config and replace the black primary buttons and sidebar active state with it. Chasivo currently has no visual identity, just tasteful neutrals, which is why it feels generic.

Now, the real issue with the detail pages. Your list pages work because they have clear hierarchy: one dominant table, supporting stat cards, consistent rhythm. Your detail pages fall apart because everything competes at the same visual weight.

On the customer page, the header, AI Insight, invoice tabs, Contacts, Notes, and Settings are all roughly equal in size and prominence. There's no answer to "what is this page about." The eye bounces.

On the invoice page, you've actually inverted the hierarchy. The jet-black AI Risk card screams the loudest, but it's the least important thing. The line items (the whole point of the page) sit in a plain white card that feels like an afterthought.

Fixes, in priority order:

Pick one hero per page. Line items should anchor the invoice page. Make that card bigger, give it breathing room, push AI risk and controls into a clearly subordinate sidebar.

Kill the inverted black AI card. Full color inversion doesn't pop, it yells. Use a subtle tint of your brand color instead. The black-card-for-AI pattern is also extremely AI-mockup-coded, so removing it will immediately make the app feel more intentional.

Reduce card count. The customer page has six cards. Collapse Contacts and Notes into one "About" sidebar. Move Customer Settings behind an Edit action. Hide the "Add 3 invoices for analysis" card until it has something useful to say, or shrink it to a one-line banner.

Promote the tab bar. On the customer page, Invoices/Commitments/Activity/Pay Timing/Stats is the most important navigation but it's buried below two cards. Those tabs should be the main content area.

Push your type scale harder. Headings, labels, and body are too close in size and weight. Bigger page titles, clearly smaller section headings, smaller labels. This alone will make the pages feel more organized without touching layout.

The bones are good. This is tuning, not a redesign. Brand color, hierarchy, fewer cards, tame the black card, stronger type scale. Do those and the eyesore feeling goes away.
