Steam e-ink template library

You are a senior product engineer. Turn the product idea below into a locally runnable MVP.

## Idea

Steam e-ink template library
Helps players and desk-setup enthusiasts create and sync e-ink themes.

## Product concept

Build a desktop companion app and template library that lets users display their Steam online status, current game, wishlist, controller battery level, weather, and calendar on an e-ink screen. The first version would not sell hardware. It would provide a setup wizard for existing screens, theme previews, a sync program, and community submissions.

## Why now (backed by facts)

Valve open-sourced Steam Machine e-ink screen-related content, and the story reached No. 1 on the HN homepage that day, with high discussion activity. This may indicate that players are willing to experiment with more personalized, low-power desktop displays.

## Direction (model inference, not independently verified)

Target user: Players who already own a Steam Deck, mini PC, or desk-setup equipment and enjoy tinkering with peripherals but do not want to write code.

Minimal entry point: Start with a single-page app and a local sync utility: users sign in to Steam, choose a template, and generate a screen layout image. Drop the hardware compatibility matrix, community store, and complex animations. Support only manual refreshes and a small set of common sizes.

The strongest case against: The strongest case against this is that the installed base of hardware and the size of the tinkering-user segment are both unvalidated. HN activity may reflect discussion of open-source news rather than willingness to pay for templates and sync software.

These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty.

## Punching above weight (model inference)

Make template pages indexable to target long-tail searches such as "Steam e-ink themes" and "game status desktop displays." Share downloadable templates in follow-up Hacker News discussions and Steam Deck and desk-setup communities on Reddit.

## Competitors & gaps (model inference)

- SteamGridDB: Focuses on game cover art and asset management. It does not handle real-time status displays on e-ink screens.
- TRMNL: A general-purpose e-ink dashboard. Its support for Steam player workflows and game-asset templates is not deep enough.
- Tidbyt: Focuses more on pixel displays and general-purpose widgets. Static e-ink layouts and player themes are not its focus.

## How it makes money (model inference)

Use free templates to drive acquisition, then monetize premium themes, sync capabilities, and creator revenue sharing through subscriptions or one-time purchases.

- Valve open-source the Steam Machine e-ink screen so you can make your own (https://www.gamingonlinux.com/2026/07/valve-open-source-the-steam-machine-e-ink-screen-so-you-can-make-your-own/)

## Deliverables

- Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery.
- Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary.
- Do not show unverified market numbers in the UI or API.
- Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge.
- If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code.
- If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype.
- When done, explain what changed, how to run it, and how to verify it.
- Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
