Every answer here comes from what the vendor publishes on its own pages, or from an official register where noted, with the source link and the date we checked it, plus the verbatim quote wherever one was published. Where we could not find anything published, we say so rather than guess.
Each page answers one question across every vendor we track, side by side.
