* chore(ui): Patch bump in tailwind related packages and framer-motion
tailwind: [4.1.6 -> 4.1.7](https://github.com/tailwindlabs/tailwindcss/compare/v4.1.6...v4.1.7)
@tailwindcss/postcss: 4.1.6 -> 4.1.7
@tailwindcss/vite: 4.1.6 -> 4.1.7
Also patch-bump of:
framer-motion: [12.11.0 -> 12.11.4](https://github.com/motiondivision/motion/compare/v12.11.0...v12.11.4)
No source changes seemingly needed, have not rerun the migrate.
* chore(ui): Run tailwind upgrade and review changes
Ran the `npx @tailwindcss/upgrade` and accepted the changes that seemed safe.
They're things like:
- `data-[closed]:translate-y-9` -> `data-closed:translate-y-8` ()swaps the square bracket syntax to a `-` modifier)
- `bg-gradient-to-*` -> `bg-linear-to-*`
- `/[*%]` -> `/*` (swap square bracket syntax for inline)
- `theme(*.*)` -> `var(--*-*)` (theme styles are exposed as variables with hyphens for dots now)
- `[background-size:*]` -> `bg-size[*]` (move the square brackets inside tag)
- `[.active_&]:` -> `in[.active]:` (new syntax for parent query)
- `!class` -> `class!` (e.g. _!overflow-visible_ to _overflow-visible!_, for [important flag](https://tailwindcss.com/docs/styling-with-utility-classes#using-the-important-flag style)
- `w-[1px]` -> `w-px` (that's a new syntax for a 1px width)
- `h-[1px]` -> `h-px` (that's a new syntax for a 1px height)
- moved `html` and `html, body` global settings in the _index.css_
Also killed off an unused `import` and blank css class.
Also picked up the two `flex-grow` -> `grow` that I missed last pass, oops.
* chore: Upgrade UI vite and tailwind packages
Vite 5.2.0 -> 6.3.5
@vitejs/plugin-basic-ssl 1.2.0 -> 2.0.0
cva: 1.0.0-beta.1 -> 1.0.0-beta.3
focus-trap-react 10.2.3 -> 11.0.3
framer-motion 11.15.0 -> 12.11.0
@tailwindcss/postcss 4.1.6
@tailwindcss/vite 4.1.6
tailwind 3.4.17 -> 4.1.6
tailwind-merge 2.5.5 -> 3.3.0
Minor updates:
@headlessui/react 2.2.2 -> 2.2.3
@types/react 19.1.3 -> 19.1.4
@types/react-dom 19.1.3 -> 19.1.5
@typescript-eslint/eslint-plugin 8.32.0 -> 8.32.1
@typescript-eslint/parser 8.32.0 -> 8.32.1
react-simple-keyboard 3.8.71 -> 3.8.72
The new version of vite required an Node 22.15 (since that's current LTS and node 21.x is EOL)
The changes to css due to the tailwind 3 to 4 upgrade were done following [the upgrade guide](https://tailwindcss.com/docs/upgrade-guide#changes-from-v3)
Done in this order (important):
`shadow-sm` -> `shadow-xs`
`shadow` -> `shadown-sm`
`rounded` -> `rounded-sm`
`outline-none` -> `outline-hidden`
`32rem_32rem_at_center` -> `center_at_32rem_32rem` (revised order of gradient props)
`ring-1 ring-black ring-opacity-5` -> `ring-1 ring-black/50`
`flex-shrink-0` -> `shrink-0`
`flex-grow-0` -> `grow-0`
`outline outline-1` -> `outline-1`
ALSO removed the **extra** `opacity-0` on the video element (trips up latest tailwind causing the video to be invisible)
FocusTrap is now not exported as the default, so change those imports
headlessui's Menu completely changed, so upgrade to the new syntax which necessitated a reorganization of the Header.tsx to enable the "menu" to still work
* Update eslint config and fix errors
