Danny White 5f9ce727c0 fix(ui): systematise control surface fills and hover borders (#48887)
## What kind of change does this PR introduce?

Bug fix / design-system token hygiene for form and selector chrome.

## What is the current behavior?

After opaque default-button fills, text fields, selects, and selector
tiles drifted apart: inputs and selects mixed ad-hoc washes, hover
borders bounced between `border-stronger` / `border-foreground-muted`,
invalid fields had no hover step, and composites like InputGroup leaked
inner hover borders.

Follow-up to #48837 (opaque button fills) where Select rest still felt
darker than Input on forms such as scoped access tokens.

## What is the new behavior?

Named control roles and one interactive border:

| Role | Fill | Rest border | Hover / focus / open |
| --- | --- | --- | --- |
| Field (sunk) | `bg-field` | `border-control` | `border-control-hover`
|
| Raised control | `bg-control-raised` | `border-strong` |
`border-control-hover` |
| Overlaying action | card → popover | `border-strong` |
`border-control-hover` |
| Invalid field | `bg-destructive-200` | `border-destructive-400` |
`border-destructive` |

- `--field` / `--control-raised` / `--border-control-hover` live in
`semantic.css` (source of truth for roles; README points there)
- Input / Textarea / InputGroup / legacy TextArea use the field ladder
(incl. invalid hover)
- Select and empty MultiSelect use raised; filled MultiSelect sinks to
field
- Default + dashed Button, CommandMenu trigger, and radio
card/stacked/large use `border-control-hover`
- Studio selector tiles aligned: Connect mode, role impersonation,
DuckLake modes, compute “Contact us”

## Additional context

`--control-raised` aliases `--card` today (role name so fill can diverge
later). Rest `border-control` / `border-strong` both still map to
`--input` via compat; the shared interactive step is
`--border-control-hover`.

## To test

1. **[Account → Access
Tokens](https://studio-staging-git-dnywh-fixcontrol-surface-tokens-supabase.vercel.app/dashboard/account/tokens)**
Open Generate / New scoped token. Side-by-side Input, Select,
RadioGroupStacked, MultiSelect. Confirm sunk vs raised fills, shared
hover border, MultiSelect flips to sunk once a value is selected. Leave
a required field empty to check invalid rest → hover → focus.

2. **[Org →
Projects](https://studio-staging-git-dnywh-fixcontrol-surface-tokens-supabase.vercel.app/dashboard/org/_)**
Hover the dashed Status filter. Hover default / filled filter buttons
when active. Confirm hover/open borders match.

3. **[Project →
Connect](https://studio-staging-git-dnywh-fixcontrol-surface-tokens-supabase.vercel.app/dashboard/project/_)**
Open Connect from the header. Mode grid tiles: hover + selected borders
match radio cards (no old muted-foreground ring).

4. **[Project →
Compute](https://studio-staging-git-dnywh-fixcontrol-surface-tokens-supabase.vercel.app/dashboard/project/_/settings/infrastructure)**
(optional)
   Compute size radios + “Contact us” tile hover.

packages/ui

Supabase's shared React component library. Built on Radix UI primitives and shadcn/ui, styled with Tailwind CSS, and used across all Supabase apps.

Usage

Import from the 'ui' package alias:

import { Badge, Button, Input } from 'ui'

Some of the components have the _Shadcn_ suffix. These components should be preferred, they're in a process of replacing the other ones.

Utilities

// deep object merge (used for themes)
import { clipboard, cn, mergeDeep } from 'ui' // clsx + tailwind-merge

// copy-to-clipboard helper

Styling conventions

  • Tailwind only — no inline styles or CSS modules.
  • Prefer shadcn semantic pairs (bg-card text-card-foreground, bg-muted text-muted-foreground, bg-tertiary text-tertiary-foreground) over hardcoded colors. Legacy utilities such as text-foreground-light and border-default are compatibility aliases only.
  • Control surface roles (bg-field, bg-control-raised, border-control-hover; CSS --control aliases raised) live in build/css/source/semantic.css. Prefer those over inventing fills. Legacy bg-control is still the accent wash alias.
  • Themes set the core --hue (or the split --surface-hue / --primary-hue), --chroma, --surface, --foreground-lightness, and --contrast inputs, plus their --muted-foreground-level and --tertiary-foreground-level hierarchy. Semantic colors are derived from them in OKLCH; --contrast: 1 is the baseline and the supported adjustment range is 0.75 to 1.25.
  • The workspace root owns the actual tailwind.config.js. The file in this package is a stub for IntelliSense only.
