v0.2.0:37 — "Limited" → "Limited discount" on launch-special meta

Adds the word "discount" so buyers don't misread the limit as a
license count. "Limited: 10 remaining" was ambiguous; "Limited
discount: 10 remaining" is unmistakable.

Landing-page dynamic tier-card JS matches in a separate commit on
the keysat-xyz-landing repo.

Cosmetic.
