# frozen_string_literal: true

# =============================================================================
# Whitelabel — Centralised brand configuration loader
# =============================================================================
# Reads config/whitelabel.yml once at boot and exposes every value through
# simple accessor methods.  All view helpers, mailers, PDF generators and
# other call-sites should use Whitelabel.xxx instead of hard-coding strings.
#
# Usage examples:
#   Whitelabel.brand_name          # => "Intébec"
#   Whitelabel.support_email       # => "support@intebec.ca"
#   Whitelabel.theme(:primary)     # => "216 77% 52%"
#   Whitelabel.email_from          # => "Intébec <info@intebec.ca>"
#   Whitelabel.sign_reason("John") # => "Signed by John with Intébec"
#
# After editing config/whitelabel.yml, call  Whitelabel.reload!  or restart.
