Browser font fallback determines the threat. When a page specifies font-family: Arial, Helvetica, sans-serif and a string contains Cyrillic а, the browser checks Arial’s glyph tables, finds Cyrillic coverage, and renders it using Arial’s Cyrillic glyphs — which are pixel-identical to the Latin ones. The CSS font stack you ship determines which column of the danger rate table applies to your users. Arial at 40.8% is a different risk profile from Didot at 19.2%.

My Voyager keyboard and Ploopy Adept trackball are mounted to a telescoping section of T-slot that allows me to stand about 1.5 meters / 5 feet away from the monitors. This reduces eyestrain from working at a computer all day and, hopefully, helps slow the progression of myopia. I used ZSA’s Tripod Mount kit and standard ball-head tripod mounts to connect the keyboard and mouse to the T-slot. This makes for easy, secure tenting of the keyboard and mouse at the perfect angle.
