/* Marketing landing page (web/landing.html).

   Used to override styles.css's tokens back to the original black/neon-green
   terminal identity for this page only. That made the whole page harder to
   read than the app it's selling (see legal.css's comment on the same
   trade-off) and put it out of step with every other public page — blog,
   tutorials, and legal all already reuse styles.css's light "workspace"
   palette. This page now does too, for the same reason: long-form marketing
   copy reads better on a light surface, and one consistent look across the
   whole site reads as more finished than a black landing page in front of a
   light app.

   The black/green identity isn't gone — it's demoted from "the whole page"
   to a couple of deliberate accents, the same way the app shell already
   does it for `.logo-badge`: fixed colors, not theme tokens, used only
   where the terminal look earns its place (the SKILL.md preview, the MCP
   connect card). */
