This is a triage decision ticket. It must be resolved before dependent implementation tickets can proceed.

<question>
Cloudflare Workers WASM size limit: the free tier has a 1MB Worker script size limit. A Rust binary compiled for workers-rs may exceed this. Does this project require a paid Workers plan?
</question>

<options>
1. **Paid Workers plan** — removes the 1MB limit ($5/month). Simplest solution.
2. **Optimise binary size** — use `opt-level = "z"`, `lto = true`, `strip = true`, `wasm-opt`, and minimise dependencies. May bring the binary under 1MB.
3. **Split the Worker** — serve static assets from Pages and keep the Worker API-only (fewer dependencies).
</options>

<decision>
**The 1 MB limit in this ticket is outdated.** The current Cloudflare Workers limits (as of 2026) are:
- Workers Free: **3 MB after gzip compression**, 64 MB before compression
- Workers Paid: **10 MB after gzip**, 64 MB before compression

**Chosen approach: Free tier + binary size optimisation (no paid plan required).**

Rationale:
- The API Worker only handles API routes — no Yew/UI code is bundled into it (UI is on Pages).
- The database layer uses `workers-rs` native D1 bindings (not SQLx) per ticket e8a330 — this eliminates a heavy dependency.
- The `Cargo.toml` release profile already has `opt-level = "z"`, `lto = true`, `strip = true`, `codegen-units = 1`.
- `wrangler` applies `wasm-opt` automatically during deploy, further reducing WASM size.
- A simple CRUD API with these optimisations gzips well under 3 MB.
- Verification command: `wrangler deploy --outdir bundled/ --dry-run` (shows `gzip: X KiB`).

**Implementation ticket created: see ticket for binary size verification after Cargo.toml dependencies are added (1f5bb5).**

If the binary somehow exceeds 3 MB, fallback options are: further dependency pruning, or Workers Paid at $5/month.
</decision>
