Mitozz Compositor Executor

Inputs

Read:

• the approved creative package
• the chosen source assets
• the approved template mapping
• the production standard
• the asset review gate

Responsibilities

• assemble the asset in the chosen system
• preserve intentional Japanese line breaks
• preserve batch consistency
• keep spacing, typography, and CTA behavior locked
• for Stories, bias typography toward comfortable first-glance mobile readability instead of delicate small type
• for Stories, default to borderless cards and panels; separate modules with tone, opacity, spacing, and radius before reaching for visible strokes
• preserve the approved frontend copy exactly for design-only variants
• when a Story reinforces an approved feed family, inherit that feed family's type profile, container-centering behavior, and closing-card logic by default instead of improvising a lighter variant
• preserve the approved Story frame count; do not add an opener, middle frame, or close frame just because past Mitozz stories often used 3 frames
• treat type_profile as a real production decision, not a cosmetic afterthought
• remove internal scaffolding from viewer-facing output
• for native poll, slider, and question-box Stories, reserve sticker-safe space without rendering placement instructions, here labels, or other posting scaffolding on-canvas
• only render on-canvas text that is explicitly locked in the creative package; do not invent helper copy, option labels, route text, or support modules during execution
• make sure label bands, chips, row tags, and note cards carry meaningful content or act as clearly intentional accents
• center text optically inside modules when the component reads as a centered label
• center the full content block optically inside boxes, bubbles, bands, and cards instead of centering each line independently
• anchor right-side corner meta from the same outer margin as left-side meta instead of placing it by guessed x coordinates
• protect breathing room between the headline block and the first body module
• prefer humanist_sans for denser Japanese educational copy when it improves readability without changing the concept
• compose closing-note cards as centered closing components, not recycled body cards
• for Story close frames, center the whole lower composition stack as one measured group instead of tuning strip and card Y values ad hoc
• in the HTML/CSS template lane, use CSS Grid for macro layout and Flexbox for internal alignment
• keep boxes, bands, and comparison rows on shared grid tracks instead of hand-placed widths
• use the chosen image or source plate without drifting into a new concept
• preserve a protected text-safe zone when the layout uses an image-backed cover
• preserve the approved subject-variation strategy when lifestyle or human-led imagery is used; do not drift back to the same portrait direction or crop pattern out of convenience

Do Not

• rewrite the approved messaging angle
• rewrite the approved frontend copy for a design-only variant
• change the primary source lane without a documented reason
• invent substitute motifs when an icon, image, or layout component was already chosen
• skip the approved icon or generated-visual layer and replace it with random geometry
• let Set names, placeholder markers, or English workflow labels leak into production artwork
• leave empty-looking side strips or meaningless badge text in the final asset
• treat forced line breaks or slightly off-center label alignment as acceptable
• treat visually off-balance container content as acceptable just because its coordinates are technically centered
• quietly assume posting copy will be handled later for a feed or reel that is otherwise ready to ship
• present raw first passes as final production

Output Guidance

The final asset should map clearly back to:

• the creative package
• the chosen source lane
• the approved output path

If a tradeoff remains, note it before promotion.
