The living-story system. Short or long dispatches that tell Doozer's WHO/WHAT/WHEN/WHERE/WHY/HOW/VISION, stamped to the moment they were written.
Postcards are how Doozer tells its own story, on purpose and over time. A Postcard is one dispatch about why Doozer exists, what it does, how, and for whom. It can be a tweet, a short note, an essay, or a quote. Admin lives at Admin → Story → Postcards (includes/admin-postcards.php); the engine is includes/postcards.php.
Seven lanes, the journalist's six questions plus a vision lane: WHO / WHAT / WHEN / WHERE / WHY / HOW / VISION (postcardDimensions()). Four formats: tweet, short, essay, quote (postcardFormats()). Audiences: everyone, entrepreneurs, investors, operators, press, local customers, for-the-record (postcardAudiences()).
Every Postcard is written "from where the story is today" and stamped with the platform version and date (as_of_version, as_of_date). As the platform changes, you write new Postcards; the old ones stay. The collection becomes the story's own changelog, readable from any moment. Evergreen cards can carry live tokens ({site_count}, {cloud_count}, {version}, {year}) so they always speak in today's numbers (postcardFillTokens()).
postcardAiDraft($dimension,$format,$audience,$voice,$brief) drafts from live platform signals (postcardSignals()) plus Doozer's ground-truth story facts, in a chosen voice. Hard rules baked into the prompt: no em-dashes, no invented facts, speak from today, plain language, no AI-slop. Returns title + dek + body for the operator to review before saving. Distinct from Marketing build-in-public posts: Postcards are the deep, evergreen story; marketing posts are transient.
postcards table self-heals on first use (FTP deploys do not run migrations). On first run, postcardSeedIfEmpty() loads 31 authored starter cards across all seven lanes (postcardSeedSet()) so the collection has a real voice from day one.
Postcards are source material: the doozer.work "Because" copy, an About page, a press kit, the investor narrative, marketing seeds. Write once, retell often. They are the human-readable companion to Atlas (machine-readable) and the distilled Doozer Story.
