Round Frames

[Tsukeruu]

Will there be round frames in the future, if not please add them

Frame doesn't currently expose a border/corner style parameter. Its implementation uses the fixed Border.TOP_LEFT, TOP_RIGHT, BOTTOM_LEFT, BOTTOM_RIGHT, HORIZONTAL, and VERTICAL class constants, so CSS/style configuration can change colors/attributes but not those glyphs.

For rounded corners specifically, the characters would normally be ╭ ╮ ╰ ╯ instead of the current square corners. Adding this cleanly would probably mean making the border character set configurable on Frame (rather than adding a one-off rounded=True flag), so other border sets could be supported without another API change.

Until then, a custom container modeled on Frame is the straightforward workaround; replacing only styling won't change the characters.
