The value of writing a brand down is not tidiness. It is that a written palette ends the argument. Six months later, at the end of a long day, nobody invents a new blue for one banner, because the blue already exists and is two clicks away.
A kit holds the colors, with the first three treated as primary, secondary and accent, three typefaces, a logo and a watermark image. From then on those colors appear in every color picker in the editor, the fonts are preselected, and the logo is available to any layer that wants it.
The part people discover later is the company profile: company name, industry, description, address, website and your own custom variables such as tone of voice or target audience. That profile is not decoration. It feeds the AI generation, so a generated design or a generated article knows who it is for without you retyping it every time.
And because a site can hold several kits, one installation can serve several brands or several clients, with the right one picked per job. Dynamic templates bind to a kit by key rather than by id, so the same template works for every client with their own colors.
