How to use hanging indent with figure captions?

[hpcfzl]

Hello, I happen to have been involved in a post where this duplicate question was posed:

Incorrect hanging indentation

The code below: #set par( justify: true, leading: 12pt * 1.15 * 1.5, ) #show figure.caption: set align(left) #let figura( body, caption: none, source: none, ..args, ) = figure( [ #context { body block(width: measure(body).width)[ #if source != none [ #align(left)[ #text(size: 7pt)[ #let prefix = [Source: ] #par( leading: 10pt * 1.15, hanging-indent: measure(prefix).width…

The TLDR is that you should probably use terms for the first and list for the second.
