v1.12.1

[1.12.1] - 2026-10-26

• Start-XKCD's P/N (and the left/right arrow keys), F, and L controls now show an in-place "You're already viewing the first/latest comic" message instead of redrawing the identical frame when you're already at that end of the archive.
• Start-XKCD's G control now validates the comic number you enter: a blank/non-numeric/out-of-range entry, or one that's syntactically valid but doesn't correspond to an actual comic (e.g. a gap in the archive), shows an in-place message instead of silently doing nothing or redrawing. Re-prompting after a failed attempt reuses the same input line -- moving up one line first if a message from the previous attempt is still showing, so it stays visible, then clearing it once you start typing again.
• Start-XKCD now hides the blinking console cursor for the duration of the viewer, restoring it on exit (including on error or Ctrl+C).
• Fixes several warnings in Start-XKCD (image not downloaded yet, high-quality fallback, no inline image protocol detected, image render failure, and Sixel's "large image, may take a while" notice) showing up in an inconsistent spot -- sometimes after the frame had already finished drawing, or interleaved oddly within it -- because they went through PowerShell's separate warning stream rather than being written as part of the frame itself, like everything else in it. All of these now render inline, in a consistent spot; the large-image notice in particular now appears before the slow Sixel conversion it's warning about (rather than only after), and gets cleanly replaced by the comic once it's ready instead of lingering above it.
• Fixes a black bar sometimes appearing under a comic's image:
  • For Sixel (Show-XKCD and Start-XKCD alike): the Sixel escape sequence's background-selection parameter was left at its default, which fills any pixel no colour run ever touches with an opaque background colour (typically black) -- this showed up as a bar under the image whenever its height wasn't an exact multiple of 6 (the size of a Sixel band), which is most of the time. Unset pixels are now explicitly left transparent instead.
  • For Kitty/iTerm2 specifically in Show-XKCD: image rendering now requests an explicit column count (as Start-XKCD already did), rather than leaving sizing to the client's own default -- avoiding a similar bar caused by a partial trailing cell row of background padding, and making Show-XKCD's image sizing consistent with Start-XKCD's.
