What's fixed

generate_data_table and generate_video_overview are fully working again, confirmed on macOS M4 with French locale.

Root causes

1. Dead tile selector
clickDataTableTile used .mat-icon, [class*='icon'] which matched SPAN.icon-container before <mat-icon>, so the === "table_view" equality check always failed silently. Fixed to target the mat-icon element tag directly.

2. False failure on slow shimmer
After clicking the tile, if shimmer-blue didn't appear within 15s the tools returned success: false. The click was triggering generation server-side but the headless browser DOM update lagged. Now returns { success: true, status: "generating" } so callers can poll with get_data_table / get_video_status.

3. data-create-button-type removed by Google
Google removed this attribute from all Studio panel tiles (Feb 2026). Replaced with mat-icon text (table_view) and jslog ID (282298) as locale-independent selectors.

Also in this release

• Studio panel waitForSelector timeout increased from 10s → 30s
• Full i18n pass: locale-independent selectors throughout (CSS classes, Material icon names, jslog IDs) — English text as last-resort fallback only
• GitHub Actions CI on all PRs + main branch protection (force push / deletion blocked, build check required)
