 * A media kit for creators who work with brands: reach per channel, who the
 * audience is, sponsorship packages, earlier partners and one campaign in
 * numbers. Channels are named by what they are (newsletter, video channel,
 * podcast), never by a platform.
 *
 *   reach      channels with followers, growth and engagement, a total that counts up, a growth line that draws
 *   audience   age as bars, a split as a ring, top regions and interests
 *   packages   sponsorship packages, pick channels and the price follows
 *   partners   earlier partners as a wall, one opens with what was made and how it went
 *   campaign   one campaign as a story, brief, content and results with a before and after
