One maintenance guide, eighteen languages¶

The filter's care card, in every language Vacuum Agent ships. It is here rather than in the README because eighteen screenshots is a gallery, not an argument.

This is the deep end of the translation work, not the shallow one. Chips and buttons are single words with obvious equivalents. This card is prose — six ordered care steps and three warnings — plus a health readout, an editable interval with its own units, and a reset. Getting it right means translating instructions someone follows with the machine in front of them.

Three details worth looking for, because they are the ones a translation gets wrong when it is only string substitution:

Turkish puts the percent sign first. English reads 100% remaining; Turkish reads %100 kaldı. The sign precedes the number, which no amount of {value}% templating gets right on its own.
French puts a space before it, and is the only one that does. English reads 100% remaining; French reads 100 % restants, and the unit spaces too — Par défaut 20 h · Max 120 h against German's Standard 20h. Of the seventeen translated packs, French is the only {percent} % and Turkish the only %{percent}; the other fifteen are {percent}%. Two languages, unique in opposite directions, and the space is authored into the string because no shared template can add it for one language alone.
The hour unit localises, not just the words around it. English Default 20h · Max 120h becomes Turkish Varsayılan 20sa · En fazla 120sa (saat) and Arabic الافتراضي 20س · الحد الأقصى 120س (ساعة).
Hebrew and Arabic mirror the whole card — title and close button swap sides, the numbered steps right-align while keeping their numbering, and the interval row reverses so Save and Default sit to the left of the field.
