Photo Collage - fotojockovic.com/collage
=======================================
Photo collage / photo grid maker: 26 layouts with 2 to 9 photos, drag and drop, pan and zoom inside each frame,
spacing, rounded corners, background colour, print sizes at 150-300 DPI and social media sizes, JPG and PNG.
Everything runs in the browser; no image leaves the device.

Our own work (MIT licence): the layout engine (guillotine templates, film strip), the gestures, the preview and
export renderers (scaled JPEG decoding with WebCodecs ImageDecoder, createImageBitmap elsewhere), the JFIF/PNG
resolution writer, the UI, texts and translations.

Shared pieces of fotojockovic.com used read-only: /static/tools/fotojock/tools/printsizes.js (standard print sizes),
/static/tools/common/i18n.js, labels.css, sheets.js, seo-block.css.
