+////
+/// Letter spacing token overrides (Pine-internal until upstream consolidation)
+///
+/// Removes the small positive tracking that `@kajabi-ui/styles` applies to
+/// Inter headings, which reads as too spread out. Body copy is normalized to
+/// `0`, and `h1`/`h2` adopt a tight tracking matching Tailwind's
+/// `tracking-tight` (`-0.025em`); the remaining heading roles sit at `0`.
+///
+/// Note: `--pine-letter-spacing-heading-6` is also consumed as label tracking
+/// by `pds-chip`, `pds-combobox`, and `pds-radio-group`, so zeroing it here
+/// removes their `0.16px` label tracking too (intentional). Removing this file
+/// would therefore restore positive tracking on those labels, not just headings.
+///
+/// Namespace contract: these CSS custom properties use the canonical
+/// `--pine-letter-spacing*` namespace owned by `@kajabi-ui/styles`. Pine
+/// redefines the values here (this file is `@use`d after the upstream import
+/// in `app.scss`, so these win) without renaming the tokens. Remove this file
+/// in the same PR that bumps `@kajabi-ui/styles` to a version that ships these
+/// exact values (`--pine-letter-spacing: 0`, `--pine-letter-spacing-heading-1`
+/// and `-2` at `-0.025em`, and `--pine-letter-spacing-heading-3` through `-6`
+/// at `0`). Component SCSS does not change.
