Step 1 · Product identity lock (always first)

Before writing any prompt, study every reference photo and write a short identity lock for the product. Paste it verbatim into every prompt this skill produces, and never let a creative instruction override it.

PRODUCT IDENTITY LOCK (do not change):
- Shape & proportions: <e.g. tall cylinder, rounded shoulders, 26 cm high, 7.5 cm wide>
- Colour & finish: <e.g. matte sage green #8FA58C body, natural bamboo lid>
- Logo & printed text: <exact spelling, font feel, position, colour — e.g. white "AURA" wordmark centred on upper body>
- Parts & details: <lid, loop, buttons, ports, seams, labels, accessories that are included>
- Must NOT appear: <accessories not in the box, extra logos, invented claims>
