Makefile

# Usage:
#   make dev PORT=<port>
#
# dependencies: none
.PHONY: build
build: index.html 

# If using custom svg icons, the pngs should be downloaded, then manually converted, then manually inlined:
# build: index.html check.svg x.svg
# check.svg:
# 	curl -o check.png 'https://em-content.zobj.net/source/microsoft/74/heavy-check-mark_2714.png'
# x.svg:
# 	curl -o x.png 'https://em-content.zobj.net/source/microsoft/74/cross-mark_274c.png'
# i used this web tool to manually convert png to svg:
# https://svgtrace.com/png-to-svg
#
# BUT the easier way is native emoji favicons

# Note that inner 'make' within this makefile also has stdout hidden,
#   due to nearly insuppressible noisy logs
#   (make[1]: Entering directory ... Leaving directory...)
#   so inner errors should go to stderr in order not to be hidden
#
# dev dependencies: envsubst, nginx, entr, bws, minbrowser
