Instruments
Two dials, and both of them are yours. Agoramores keeps them in this browser — nothing here is an account, and nothing here leaves the machine except the one line Obsidian is told about the theme.
Light and dark
Every theme is struck twice: once in its own lighting and once in the other one. The switch moves between them without changing the month. Whatever your device already prefers sets it on a first visit; after that, this stands until you move it.
Night mode
Theme
Left alone, the site wears its default — the struck card. Pick any of the others below to hold it there instead, or hand the wheel to the calendar and let it wear the month it is. Either way it stands until you move it.
