/* ============================================================
   Lentix website -- production styles
   Single-theme (midnight) extraction of the Claude.ai design
   handoff at docs/design/mockups/lentix-website/. Graphite +
   daylight variants from the original mock are intentionally
   dropped -- they were design-review variations, not shipping
   themes. Midnight matches the app's #0f0f12 background, the
   single brand register Lentix ships on.
