Earth Day herbarium sheet
Earth Day as a herbarium sheet — a pressed fern frond taped to a cream mounting sheet with strips of gummed linen, and a museum-style specimen label carrying the logo, the greeting as the specimen's name in italic serif, the post's note, and the date and who it is from in handwriting.

When the AI picks it
MarketiQ’s Creative Director favours the Earth Day herbarium sheet for posts that start a conversation, teach or announce news, when the message is one sharp insight. It is built first to start a conversation.
It reads each post’s goal and shape first, then its own words, the platform and the facts you have, and offers this template only where it fits.
Who it’s for
Any business. Nothing in it assumes what you sell, so the Director can offer it to a software company, a café or a coaching centre alike — whenever the post fits.

What it needs
The Director offers it only when these exist. Without them it simply picks another template.
- A post about Earth Day, close to the date: it is offered only then
Rules the AI follows
Word for word from the template library. The Director follows the copy rules when it writes into the template, and the visual review checks every creative against the visual rules.
Copy rules
- Greet the day in the brand's own voice, from the post; no offers, prices, discounts or calls to buy (festive sales have their own formats).
- No invented names, numbers, dates or claims; a date shows only when the post gives it.
- No environmental claim (carbon, recyclable, plastic-free, trees planted) unless the post states it exactly.
Visual rules
- A cream mounting sheet on a deep brand ground; a pressed fern frond (a curving rachis with paired pinnae shrinking to the tip, each with a midrib) in a deep brand green-or-shade, held by three strips of white linen tape.
- A specimen label with a fine rule border: the logo and 'Specimen', the greeting in italic serif, the message, and 'Date' / 'From' rows in handwriting; the website on the sheet. No figures.
