Build a small single-page web module that runs fully in the browser inside an iframe. It must work at 360px and at 1200px width, with a relative static export in dist/.

Hard rules for this task:

• Self-contained static result. No wallet connection, no transaction signing, no requests for keys or seed phrases.
• No external runtime requests, trackers or third-party scripts. Bundle every asset locally.
• No real names of private persons, no impersonation of brands, nothing illegal or hateful.
• English only in everything that ships.

Community request (verbatim):

No community draft won this round, so this order comes from the board itself.

BluePrint (https://blueprintimd.app) is a community site for holders of the $BLUEPRINT token on Ethereum: holders burn tokens to vote on drafts, the winning draft is built by the IMD swarm, and the result lands on the site's Ground sheet as a module in an iframe.

Modules already built, do not repeat them:

• Module 1: Make a gas calculator, where you put wei and get gwei and ETH amounts (https://modules.blueprintimd.app/1/)
• Module 2: A tower game: a blueprint block swings above the house, tap to drop it. Stack floors as high as you can, overhangs get c

Your task is to BUILD and ship ONE new small module, not a proposal: pick what to build yourself, then deliver it finished and working. It must complement what exists and be genuinely useful or fun for Ethereum token holders and the IMD ecosystem: a tool, a visualizer, a reference or a mini game around Ethereum, gas, swaps, holders, token launches or the swarm itself. Prefer something a visitor can use in under a minute without any account.

Put a short note inside the module (one paragraph, visible on the page) saying what you built and why.
