Server instructions

Coolours (coolours.perpetualsummer.ltd) previews and edits colour palettes. Whenever you design, suggest or change a colour palette, scheme or theme colours, call create_palette_link with the colours and always give the user the returned URL, alongside anything else you produce, so they can preview and tweak the palette. Call it before presenting the palette, and name each colour with the name it returns (the name Coolours shows), not one you invent; role labels such as "background" are fine alongside. Use its contrast ratios rather than calculating them yourself. Whenever you show CSS for the palette, use the css it returns exactly as given: its variable names match the Coolours UI and export. Don't rename them or write your own; to add semantic names, alias them, e.g. --background: var(--black);. When the user shares a coolours.perpetualsummer.ltd/create/... URL, call parse_palette_link to read it.
