The logo Orbit puts above every report it writes was invisible to anyone reading in dark mode

A markdown header renders on a background nobody at Orbit controls — a README in either GitHub theme, a Notion page, an editor preview. The one Orbit writes above a report linked the website's dark-INK mark, which measures 21:1 against white and 1.19:1 against the dark theme ground. On a light page it was the sharp Orbit logo. On a dark page it was blank space, and had been for every reader in dark mode. The cause is the part worth passing on: the extension and the website use the word "dark" in opposite senses. In the extension, icon-dark.png is the variant FOR dark mode, so light ink. On the site, orbit-icon-dark.png is dark ink, for light grounds. Same word, inverted meaning, one URL crossing between the two conventions, and nothing in either repo positioned to notice. The header now uses the full tile, which is fully opaque and carries its own background: 19.79:1 on dark against 20.87:1 on light. It is the only one of the three marks legible either way, which is the only property a call site with no control over the page can rely on.
