  description

  Hero Tenaga compares your TNB electricity bill under both Domestic
  General and Domestic TOU (Time-of-Use) tariffs using your actual
  half-hourly usage data from your myTNB SmartLiving dashboard.
  
  WHAT IT DOES
  
  - Reads your usage data for any billing period you specify
  - Calculates your bill under both tariffs at full RP4 rates,
    including AFA prorated by calendar days to match TNB's calculator
  - Tells you whether switching to TOU would save you money this month
  - Shows your peak versus off-peak split, daytime versus nighttime
    split, and hourly load patterns across weekdays and weekends
  - Tracks your bills over time so you can compare across months,
    with controls to remove individual bills or clear all stored data
  - Benchmarks your peak share against other Hero Tenaga users
    (opt-in via the contribution survey)
  
  WHO IT'S FOR
  
  Malaysian residential electricity customers currently on Domestic
  General tariff who want to know whether switching to Domestic TOU
  would save money based on their actual usage pattern.
  
  If you are already on Domestic TOU, the extension currently shows a
  notice that full TOU-user features (track peak share over time,
  benchmark against others) are coming in a future release. No analysis
  is shown for TOU users in this version to avoid presenting numbers
  that have not yet been validated against real TOU bills.
