Previously a tier's featured (launch-special) discount auto-applied
silently at payment time but the discount-code input was empty,
leaving buyers unsure whether they needed to type anything to claim
the slashed price.
Now: when a tier has an active featured discount, selectTier()
pre-fills codeInput with the code string and flips into the
"applied" state — appliedCode set, status badge shows "Launch
special applied". The price card has always rendered the
struck-original + discounted-current price; this change just makes
the form match what's already visually claimed.
New `autoAppliedFeatured` flag distinguishes auto-populated codes
from buyer-typed ones:
- On tier switch, the reset block also clears the input when
autoAppliedFeatured was true (the prior featured code doesn't
necessarily apply to the new tier; better to start fresh).
- Buyer-typed codes are NOT cleared on tier switch — they may be
valid for the new tier, and the buyer can hit Apply to check.
- Any keystroke in codeInput, or a successful manual Apply, flips
the flag to false.
JS / template only; no API or schema change.
