fix: batch theme like queries - #35

Convex JavaScript generated API api import useQuery anyApi generated API references query return typing official docs
💡 Result:
In Convex, code generation is the recommended approach to achieve end-to-end type safety for your API [1][2]. By running the command npx convex dev, Convex generates a module at convex/_generated/api.js (and the corresponding .d.ts file) which exports the api object [3][4]. When using this generated api object with the useQuery React hook, TypeScript automatically infers the argument and return types based on your backend function definitions [4][5][6]. Key points regarding typing and usage: 1. Generated API (api object): This object provides a type-safe reference to your Convex functions [3][7]. It is preferred over anyApi because it provides better autocompletion and static type checking [8]. 2. useQuery Return Typing: The useQuery hook is typed to return the query's result type (as inferred from your handler's return value) or undefined while the query is in its initial loading state [9][4][6]. The signature is: useQuery<Query>(query: Query, args: Query["_args"] | "skip"): Query["_returnType"] | undefined [6][10]. 3. Manual Type Extraction: If you need to manually extract types for component props or other helpers, you can use the FunctionReturnType utility from convex/server alongside your generated function reference [5]: import { FunctionReturnType } from "convex/server"; import { api } from "../convex/_generated/api"; type MyData = FunctionReturnType<typeof api.myFunctions.myQuery>; 4. Alternative (No Code Gen): If you are not using code generation, you can use anyApi from convex/server to create function references, though this lacks the automated type safety provided by the generated api object [3][8].

Use the generated Convex API type for likes.state.
Replace the handwritten result assertions in src/components/LikeButton.tsx and src/components/CommunityGrid.tsx with the generated api.likes.state reference. The current anyApi calls bypass TypeScript checks for changes to convex/likes.ts#state.

The gallery currently opens one count query and one viewer-like query per theme card. With 33 cards, that turns one page load into 67 Convex function calls.
This adds one likes.state query that returns the counts and the signed-in viewer state together. The gallery and detail page consume that shared result. The old query endpoints remain during the rollout for cached clients.
Production Convex was deployed first so the site can switch to the new function safely.
