[Bug] Desktop: stats boxes fall below Moleskine cover instead of beside it

[realproject7]

Problem

The CSS grid-template-areas change (PR #825) broke the desktop layout again. Stats boxes and CTA button are in a full-width row BELOW the cover+info area, not in the right column next to the cover.

Mobile view is now perfect — DO NOT touch it.

Root Cause

The grid-template-areas on desktop is 'cover info' / '. stats' — this creates a separate ROW for stats below the cover/info row. What we need is for stats to be WITHIN the info area, not a separate grid row.

Solution

Desktop only (sm+ breakpoint) — keep the mobile grid-template-areas unchanged:

Option A: On desktop, change to a 3-row grid where the cover spans all rows:

sm:[grid-template-areas:'cover_info'_'cover_stats'_'cover_cta']
sm:grid-rows-[auto_auto_auto]

With [grid-row:1/span_3] or [grid-row:1/-1] on the cover so it spans all rows.

Option B: On desktop, don't use grid-template-areas at all — just put stats inside the info area as a nested element (like PR #819 did) using sm: visibility. Keep mobile grid-template-areas as-is.

CRITICAL: Do not change the mobile layout. It is perfect right now.

Acceptance Criteria

• Desktop: stats boxes sit to the RIGHT of the cover, below the info text, with spacing
• Desktop: stats do NOT fall below the cover section
• Desktop: "Add a new Plot" also in the right column
• Mobile: NO changes — current mobile layout must be preserved exactly
• Spacing between info rows and stats on desktop (mt-5 or mt-6)
