V3 Notes

There seems to be a couple of ways in which footnotes appear. In "technology isn't a magic wand": https://github.com/geeksforsocialchange/gfsc-v3/blob/fbd907738072f3e780666219890fd2ace1db12b8/content/blog/2021/technology-isnt-a-magic-wand/index.md?plain=1#L54 https://github.com/geeksforsocialchange/gfsc-v3/blob/fbd907738072f3e780666219890fd2ace1db12b8/content/blog/2021/technology-isnt-a-magic-wand/index.md?plain=1#L92

and in "Making a place for technology in communities"

https://github.com/geeksforsocialchange/gfsc-v3/blob/fbd907738072f3e780666219890fd2ace1db12b8/content/blog/2019/placecal-capabilities-approach/index.md?plain=1#L41 https://github.com/geeksforsocialchange/gfsc-v3/blob/fbd907738072f3e780666219890fd2ace1db12b8/content/blog/2019/placecal-capabilities-approach/index.md?plain=1#L476

There is also the remains of this JS? https://github.com/geeksforsocialchange/gfsc-v3/blob/fbd907738072f3e780666219890fd2ace1db12b8/static/assets/js/main.js#L16-L20
