Spike: see whether it’d make sense to switch to an Eleventy build

[frankieroberto]

Would this be sensible? Could it be done?

Pros:

• save 💵 on Heroku hosting
• might make it easier to switch to GOV.UK official branding in future?

Cons:

• might take a fair bit of Eleventy wrangling
• remove the ability to do anything dynamic at runtime (although we’re not at the mo)

To-do:

• Get basic site build working
• Page per service based upon a separate data file per service
• Page per topic (in data/themes.json)
• Page per organisation based on the unique organisations referenced in service data files
• Page per phase
• Other misc pages referenced in footer
• Convert most of lib/data.js into Nunjucks filters?
