Committed unformatted again: I piped the check through grep, so the task's failure never reached the shell's exit status and the chained commit ran anyway. Check exit codes, not output. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

/**
|
|
* A chevron, pointing up or down.
|
|
*
|
|
* Drawn rather than set in a font: a chevron from an icon font is one of the glyphs a system font
|
|
* may simply not have, and the reader who gets an empty box instead is never the one who wrote it.
|
|
*
|
|
* One composable for both directions rather than two that differ by a minus sign -- the pair would
|
|
* drift, and the drift would be a bug in exactly one direction.
|
|
*
|
|
* It draws no label of its own, so every caller owes it a `contentDescription`: this is the whole
|
|
* of what assistive technology has to go on, and it is also the answer to "what was that arrow for"
|
|
* six months from now.
