All flagged scripts run under bash (shebang or '# shellcheck shell=bash'), so
[[ ]] is safe. Positional parameters in helper functions are copied into named
locals, and helper functions end with a bare 'return', which keeps the exit
status of the last command (no behaviour change, notably for sha256 under
pipefail). packaging/linux/postinst.sh is POSIX sh and is left alone.
Workflows and packaging adapted from the craftrules playbook (release environment with the twelve
signing secrets, new WiX upgrade code, .dxf/.dwg file associations), app icon set (hicolor, icns,
ico), docs/releasing.md. MTEXT now opens a text editor window for its contents.
