docs(explainer,readme): the page says what Groundwork does, including the proof

[Tradebaas]

What changed and why

Both front doors were audited against the repo instead of against memory: all 21 skill cards
checked against each skill's own description:, the gate cards against the registry, plus the
six reason tabs, the lifecycle phases, the "what lives where" table and the requirements. Three
mismatches, all in the same direction of harm: the page claimed less than the framework does.

The copy route was missing entirely. Every push already unpacks a fresh copy, walks it to a
first guarded commit and throws it away again. That is the exact claim both documents open with,
and neither mentioned it in any wording, in the release where it shipped. It is a gate card now,
placed next to the self-test card whose logic it extends, and one sentence in the README beside
the same idea. Both are careful about what they promise: the build turns red on the commit that
broke the route. Neither says a merge is blocked, because drill is not a required status check
(gate and trace are).

code-review was wrong, not merely thin. The card said "two axes". True before the security
axis landed in PR #24, and it survived the rebuild that made this page English. It now names the
gate-weakening scan, the two always-on axes and the conditional security axis, which is the thing
a reader on the "Safe" tab is being promised elsewhere on the same page.

comply listed four regimes where the register carries nine. It now also names the product
and cyber security duties, and says the dates are verified against the official source.

Everything else matched: 21 cards for 21 skills, every named skill exists, the nine gate cards
describe real gates, and the three counts on the page are derived by explainer-stats rather
than typed.

Verified by

node checks/check.mjs green, and the page exercised in headless Chrome rather than read as
source:

• 10 gate cards render (was 9), every icon path resolves, none empty
• the new card sits between Self-test and And the rest, and the two-column grid lands on
  five even rows instead of four plus an orphan
• 21 skill cards render; both corrected texts wrap inside their card without overflow
• derived counts unchanged and still matching the repo: 21 skills, 21 checks, 19 decisions

Screenshot check was done on a scratch copy with the scroll-reveal forced visible and the
sections above hidden, because a static shot of the real file only captures the hero. The DOM
assertions above ran against the unmodified file.

Not verifiable here: how the section looks on a real phone. The grid collapses to one column
under 680px by an existing media query that this change does not touch.
