Fixes

• Buttons and chips now respond to your cursor. Hovering a button, a chip, a list row or an icon button used to change nothing on screen, so there was no way to tell what was clickable until you clicked it. They now shade as the cursor reaches them, and shade further while you hold the mouse down. Filled buttons keep their colour and simply deepen, so the meaning of the colour is unchanged. Nothing about this reaches the phone apps, which already respond to a fingertip.

• A draft you cannot see now looks like one that does not exist. Four read endpoints for an argument — its logic, its reactions, its full contents, and its participant list — used to answer differently depending on whether the argument was real. If you asked for one you were not allowed to see, they said so; if you asked for one that did not exist, they said that instead. Anyone could tell the two apart without signing in. All four now answer identically, so an argument you have not published gives nothing away.

• A reactions request with an unusable id no longer fails as a server error. Asking for the reactions on an argument id that is malformed, or that names nothing, left you with nothing to read. It now answers the same "not found" as every other read.

• Reporting an argument now reaches our moderators. The report button on an argument used to send you to a page that pointed at our Discord. It now opens a short form — pick a reason, add a note if you want — and files the report directly. If you had already reported that argument, it says so rather than filing a second one.
