devenv v2 requires devenv.nix to exist even when the full shell configuration lives in flake.nix via IHP's devenv.flakeModule. Contains project-specific overrides (GHCRTS, tailwind process); IHP core (postgres, ghcid, RunDevServer) still comes from the flake module. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# IHP's flake module (flake.nix) provides the full devenv shell via
|
|
# `inputs.devenv.flakeModule`: Haskell toolchain, PostgreSQL, ghcid,
|
|
# and RunDevServer. This file satisfies devenv v2's file-presence
|
|
# requirement and adds project-specific overrides on top.
|
|
#
|
|
# Duplicates the settings from flake.nix devenv.shells.default so they
|
|
# are applied under both devenv v1 (flake path) and devenv v2 (this file).
