Reverses the position the previous commit took. Hardcoding it made a value that gets flipped without a code change require a commit and a merge to flip, which is backwards — and it is the operator's call, not the file's.
No default, deliberately. `${DEMO_MODE:-false}` is the obvious form and the wrong one: a default decides whether the shop takes money on the operator's behalf, silently, whichever way it points. Having none is safe rather than fragile because `checkDemoMode` is strict — an unset stack variable substitutes to an empty string, and anything that is not exactly `true` or `false` refuses to boot naming DEMO_MODE. That strictness is the whole reason interpolating this one is defensible, so the line says so.
The compose guard had to learn the difference. It hands each deploying file's entries to the real validator, and a literal `${DEMO_MODE}` is not a value `checkDemoMode` accepts, so both the DEMO_MODE assertion and the validateEnv check failed the moment the file stopped holding a literal. Each deployment now declares the stack variables it supplies, and a bare `${VAR}` named there resolves to the declared value before the file is validated. Every other bare `${VAR}` stays opaque exactly as before — those are secrets, and what is checked of them is that the line exists.
Be clear about what that guard can prove. It cannot see Portainer, so it does not verify the stack actually holds `true`; nothing in this repository can. What it does is keep the intent beside the file and make the pair inseparable — hardcode the compose line and the registry disagrees, change the registry and it no longer describes the file. The runtime half is the boot check, which fails loudly rather than falling back. Verified by mutation: hardcoding `false` fails the DEMO_MODE assertion, and deleting the line fails that and `validateEnv`.
Restoring real payments is now two Portainer values and a redeploy, with no commit — which is what #190 asks for.
