How this house is meant to be built.

The occupied ground

A wearable that filters the body’s own light and returns selected bands with a mirror — no battery — is already patented (US 11,857,799, Soletluna Holdings / LifeWave). Their commercial form is an adhesive patch sold through direct selling, with reported 2024 revenue in the hundreds of millions. That is not an invitation to copy the claims. It is a fence.

Adjacent, legal categories: structural-color jewelry (dichroic film, decades of prior art), mineral-ceramic far-infrared yarns (a textile class with its own owners), and powered photobiomodulation devices (FDA-facing, different product). Elytra sits in the first two. Not the third. Not the patent.

Unit economics

Patches win on consumable repeat. Jewelry wins on margin and brand. A cuff at $248 with a landed cost under $40 is a real DTC product. A $2B outcome is not a default. Red-light devices as a category are roughly a mid-nine-figure market, not a vacuum. Direct selling can scale a weak SKU; it also attracts FTC attention on earnings claims.

We sell a numbered first run, not a downline. If this site ever takes real money, checkout will be ordinary e-commerce, with copy that survives a lawyer.

Make it, legally

1. Provisional patent only on construction we actually invented.
2. Do not claim disease treatment. General wellness / fashion only until there is data and a regulatory path.
3. Source film from optical-film converters; metal from a jewelry shop; knits from a mill that already runs ceramic yarns.
4. Landed cost, then price at 5–7× for jewelry, 3–4× for textile.
5. First 500 through this list. Photograph well. Do not run ads that a scientist would mock.
