docs: every C# block compiles against the packages as built; Examples and Roadmap pages for 1.19.0; direct labels and axis colours; stale claims corrected The wiki suite compiles the pages: 195 programs compile, 190 of 192 did not before. Unclosed fences in Styling are closed. Examples.md opens with 1.19.0 and its pictures; Roadmap.md lists what is done and what is still to come, with the reason for each; the pages say what WithDpi, SaveOptions, the MAUI view and the 3-D light do today.
The wiki has a Verso page, and Notebooks points at it Verso is the open-source notebook that replaces Polyglot Notebooks, and MatPlotLibNet.Verso is the extension that draws this library's charts in one of its cells. The new page says what a cell looks like, what happens to a chart taller than the cell, what a failed render shows, and why the package carries the extension and nothing else. Notebooks now names Verso as the replacement for notebook work and MatPlotLibNet.Interactive for a chart outside one, and says the package is frozen rather than merely unmaintained. The Package Map gains its section, the sidebar its entry, and the front page announces 1.18.0.
