The signup page says once that email is optional, and its passkey offer is one plain line #8626

The /signup passkey offer is now one line, "Or skip the password and use a passkey: your fingerprint, face or device PIN." It no longer mentions email. I haven't added the before and after screenshots at phone width in light and dark. This sandbox can't take them, so they're still missing from the pull.

• Email hint: unchanged. "Optional. Given, we send a link to prove it." is now the only place the form says optional.
• Not touched: /signin and the passkey-only signup. The change is one paragraph in src/web/pages/site.ts, inside the password-signup passkey block.
• Test: the render test in test/signup-password.test.ts now strips the form to text. It asserts "optional" appears exactly once, case-insensitive, and that the new passkey line is present.
• Checks:

- signup-password, signin-page and site-field-errors pass (20 tests). - tsc --noEmit is clean. - bun scripts/design-lint.ts passes. - I did not run bun scripts/gate.ts, because it didn't run in my last command.

• To try it: open /signup on the preview. With JavaScript on, the passkey block shows under the password field.
