Three marks were put on a real panel and judged at the size the bar actually draws them. A bell sat inches from Plasma's own notification bell and meant something entirely different. A handset with an outgoing arrow read as a telephone feature. Breeze has people and it has telephones and the two never meet, so this is drawn in Breeze's language instead: an adult, a child, and one small speech bubble, on Breeze's 22-unit grid with its ColorScheme-Text class, so it recolours with the session and needs no second file for the light theme. Quick Launch carries it. The Icon widget copies the entry into the user's home so an update could never change it; a task manager reads the entry live but also shows every running window, which filled the auxiliary corner with the lesson's tasks. One defect found on the way, and it affected the Wonder Ink icon that is already shipping: gdk-pixbuf recognises an SVG by sniffing the first bytes, and a licence-length comment above the opening tag pushes it out of that window. Every GTK program reported "couldn't recognize the image file format" while Qt rendered the same file happily. The comments live inside <svg> now. Co-Authored-By: Claude Opus 5 <[email protected]>
