The sidebar's foot is now aligned with the rest of the sidebar. The Quick setup card's edges sit on the same column as the words and icons above it, 16px in on both sides. Upgrade plan and the rail's account share one line on the pane's bottom edge, beside the rail and in the phone drawer, the same way the title row and the first rail icon sit on its top edge.

This PR also adds one optional prop, upgrade, on Host. A host that draws its own plans passes it, and every upgrade press in the package then calls it and does not navigate. Version 0.3.13.

The foot

Measured on hanzo.ai's own export, signed in on the free plan with the card showing:

	before	after
card left..right (1440)	52..276	60..268
text column ('Recents', New chat icon)	60	60
card title	fits at 224px wide	fits at 208px (Setup padding $2, a row's inset)
Upgrade row centre vs account centre, 1440	862 vs 870 (hanzo.ai, patched rail)	870 vs 870
Upgrade row centre vs account centre, 390 drawer	818 vs 810 (this package)	818 vs 818
list end to card / card to foot row	8 / 8	8 / 8

Beside the rail the sidebar's foot had 8px of padding. In the drawer it had none, while the rail's foot kept its 8px. So the account and Upgrade plan were on one line in one layout and 8px apart in the other. Now both feet are 0 (Sidebar and Rail pb), and the foot row stands on the pane's bottom edge. The space above the card is Recents' own flex fill and nothing more.

The upgrade link

The press already went straight to https://hanzo.ai/pay/cart?returnUrl=..., which answers 200 with no redirect. Nothing in this package writes billing.hanzo.ai. (The billing: "https://billing.hanzo.ai" in hanzo.ai's chunks is @hanzogui/shell's links map, read only by its Billing links, none of them an upgrade press.)

payUrl is still the one writer of the checkout address. On the checkout's own origin it now writes a path (/pay/cart?...); from any other origin, and in the prerender, it writes the whole address. term follows the same rule (local).

pay chooses the plan from ?plan= itself and reads what the viewer holds from their subscriptions, so no parameter for the viewer's current plan is added.

The host's plans

Host takes upgrade?: () => void. Every upgrade press goes through useUpgrade (host.tsx):

• the sidebar's Upgrade plan and the shell's
• Chat's header
• the bar's Upgrade
• the account menu's Get Pro and its plans row
• Dev's plans (leave)
• the composer's usage
• Settings' model controls

Chat's paywall (Upgrade.tsx) hands its ask to the host instead of drawing its dialog. The prop is on Host rather than App because the shell's presses are drawn outside App.

Checks

• pnpm typecheck
• pnpm lint:design
• pnpm build, and the dist root loads in Node
• vitest run: 61 files, 577 tests

New tests:

• The foot's shared padding and the card's inset (fails on the old source).
• A host's upgrade takes Dev's plans press and the page goes nowhere (fails when useUpgrade ignores it).
• payUrl and term on hanzo.ai, on other origins (a lookalike included) and in the prerender.
