Scenario value of Add Border in polaroid
`polaroid-style-border` supports 拍立得留白风场景. Keep border weight, readability, and destination consistency stable with pilot validation, staged rollout, and anomaly logging.
`polaroid-style-border`: fix bottom-heavy rails, reserve two ink lines for captions, export at 1.5–2× final long edge
- Polaroid vibe lives in the weighted bottom rail, not four equal gutters: set long-edge padding percentages plus a thicker bottom factor (often ~1.2–1.6× the sides), then carve a caption band tall enough for two handwriting lines. Keep subjects off the inner rail so shadow noise doesn’t read like a cheap sticker edge.
- Paper grain should appear only on zoom; shadows stay as whisper contact tones. Composite samples on charcoal chat bubbles and clean white feeds—off-neutral whites show instantly. Adjust the matte, not a global filter stack, when the frame clashes with UI chrome.
- If handwriting arrives later, still export with headroom on the final long edge (1.5–2×). For week-long activations, use `YYYYMMDD_eventcode_index` plus a CSV mapping shoot, photographer, and preset id; print postcards need `_print` variants without screen-only glow.
Polaroid border FAQ: ink resolution, dark-mode gray, mixed aspect, press fidelity, batch drift
We pen captions on the wide bottom mat—what pixel budget survives WeChat recompression without turning strokes into mush?
Target 1.5–2× the shipped long edge and proof at ~2× phone CSS width so thin strokes keep forks. If you only export to the platform cap, JPEG passes will eat ink first—consider vector lettering composited on top instead of betting solely on raster handwriting resolution.
Mats look crisp on a calibrated display but read as dingy newspaper on dark cards—monitor issue or color science?
Usually simultaneous contrast against real UI. Capture on-device screenshots, log the hex white, and adjust toward a neutral cool gray if needed. Sign-off happens on phone dark feeds, not sRGB perfection on a desk monitor.
Same pixel padding on portrait vs landscape breaks the “one film stock” illusion—why?
Humans judge against the long edge; fixed px rails feel thinner on landscape. Switch to long-edge or short-edge percentages and lock one bottom-weight factor. Preview a wall grid before batching so singles pass but the mosaic still matches.
Clients want postcards from the digital polaroid frame—can glow and soft corners ship to press unchanged?
Assume not: presses eat micro-shadows and round corners dot differently. Rebuild strokes for CMYK soft proof minimums and decide whether glow survives; keep `_screen` vs `_print` filenames so ops never ships the mood board to a cutter.
Seven-day campaigns risk preset drift when one day is re-exported—how do we catch it early?
Lock quartets read-only; replacements swap content only. Store `preset_id` and file hashes in the ops sheet—if the hash changes without a ticket, roll back the whole bundle instead of patching the complained tile.
