Code style

Surplus conventions are documented in the repository’s docs/conventions.md and enforced with Biome (@biomejs/biome) at the root.

Highlights

Bun only — no npm / Node runtime requirement for app code; TypeScript runs under Bun.
Type aliases, not interfaces — except when extending third-party types.
No any — prefer inference and precise Zod schemas from @surplus/types.
camelCase — tables, columns, files, CSS variables, and DOM element IDs (interactive elements use structured IDs such as {route}{section}{control}).
Semantic design tokens in the client — bg-background, text-foreground, etc., not legacy palette class names.
ORPC for all client ↔ server calls; forms and mutations follow TanStack patterns described in docs/architecture.md.

# Write fixes where safe
bun run lint

# Typecheck all @surplus/* workspaces
bun run typecheck
