Hand-Rendered Explainer

Provide verified topic/facts/source notes, audience/teaching goal, preferred structure and exact labels/claims for later typesetting. Resolve essential factual or rights gaps before generation.

Reduce the material to one teaching claim and three to six supporting facts, retaining qualifications that affect meaning. Choose one evidence grammar and plan the reading path; do not invent numbers or connections to make the design more dramatic.

Write a fresh English brief specifying marker-line character, restrained accents, open spacing and blank exact-copy zones. Keep small text out of the request and exclude copied scenes, protected identities, logos and watermarks. Review before the paid task.

Use Node.js 20 or newer with a FAL account and FAL_KEY from the environment. One paid request produces three high-quality 1536×864 PNG variants. The wrapper fixes these dimensions and does not calculate data graphics or verify source facts.

Preserve provider-task.json and the approved prompt. Once the request ID is saved, resume with the same prompt/output directory; recorded failed tasks are not automatically resubmitted. Persistence follows the submit response, so inspect provider history before retrying an uncertain response or failed write. Keep approved copies separate because resumed downloads may overwrite matching filenames.

Compare every alternative with the source for the teaching claim, factual relationships, data geometry, order and hierarchy. Check actual dimensions, distinction and accessibility. Add exact labels/citations with a deterministic tool and use small inline SVG for functional legend/callout cues. Deliver only after the final words and visual relationships have been reviewed.
