fix(docs): re-vendor the platform tokens the docs skin had fallen behind

[gianlucamazza]

test_tokens_match_platform has been failing on main (noted in #103) since mklang-platform 1e80671 added six --surface-* tokens to web/shared/tokens.css. This re-vendors the :root block exactly as the test's message instructs; the file header is unchanged.

The test skips on CI (private sibling repo), so only a local checkout with both repos could see the drift.

Checks: tests/repo/test_brand_assets.py 4 passed; full suite 682 passed, 1 skipped.
