Richie e4ce243e57 Add GEMINI.md for Antigravity IDE project rules
- Mirrors CLAUDE.md conventions for cross-tool consistency
- Hard rules: no hardcoded values, token access patterns, atomic tiers
- Scoped for visual polish work in Antigravity browser agent

FA 2.0 Design System — Antigravity Rules

Project context

Funeral Arranger (funeralarranger.com.au) design system rebuild. Parsons is the client. The design language must be warm, professional, trustworthy, and calm. Users are often in distress.

Tech stack

  • React 18 + TypeScript
  • Material UI (MUI) v5
  • Storybook 8+ (running on localhost:6006)
  • Style Dictionary for token transformation
  • W3C DTCG token format

Hard rules

  1. Never hardcode colours, spacing, typography, or shadows — always consume the MUI theme (theme.palette.*, theme.spacing(), theme.typography.*) or CSS custom properties (var(--fa-*))
  2. Never use raw hex values in components — map to semantic tokens
  3. Follow atomic design tiers: atoms → molecules → organisms → templates → pages
  4. Component folders: PascalCase, each contains ComponentName.tsx, ComponentName.stories.tsx, index.ts
  5. Token files: camelCase in tokens/ directory (primitives → semantic → component tiers)
  6. CSS custom properties prefix: --fa-
  7. Error styling uses copper (#B0610F) not red — this is intentional for grief-sensitive context
  8. Copy tone: warm but not gushy. Understated empathy. Let UI structure be the empathy.

Token access convention

  • Semantic tokens: theme.palette.*, theme.typography.*, theme.spacing()
  • Component tokens: var(--fa-component-property-state)
  • Never mix — semantic via theme, component via CSS vars

Storybook

Dev server runs on localhost:6006. When verifying components visually, navigate to the specific story URL. Story IDs follow the pattern: /story/{tier}-{componentname}--{variantname}

File structure

src/components/atoms/       — Button, Input, Typography, Card, etc.
src/components/molecules/   — SearchBar, PriceCard, ServiceOption, etc.
src/components/organisms/   — Navigation, Footer, ArrangementDialog, etc.
src/components/templates/   — WizardLayout
src/components/pages/       — IntroStep, ProvidersStep, etc. (wizard steps)
tokens/primitives/          — Raw values (hex, px, font names)
tokens/semantic/            — Design intent (color.text.primary)
tokens/component/           — Per-component tokens

When making visual changes

  1. Make the code change
  2. Open the Storybook story in the browser to verify
  3. Screenshot and check spacing, alignment, visual weight
  4. Self-correct if something looks off before presenting
