Reconcile PR Conflicts

Changes Made

• Rebased the PR branch onto origin/main.
• Resolved the only manual conflict in apps/web/app/terminal.test.ts.
• Kept both the synthetic admin visibility test and the ticker parsing helper tests.
• Preserved the rest of the branch changes while letting Git auto-merge the terminal stylesheet and app shell updates.

Context

The PR already contained terminal UI hardening and responsive adaptation work. The base branch moved underneath it with additional terminal test coverage, so the conflict needed to be reconciled without dropping either set of expectations.

Important Implementation Details

• The conflict was limited to test imports and test blocks, not runtime terminal logic.
• The merged test file now imports both isSyntheticAdminVisible and parseTickerFilterInput.
• An explicit undefined case was kept for the admin visibility helper to preserve the stricter branch-side regression coverage.

Validation

• Ran bun test apps/web/app/terminal.test.ts apps/web/app/routes.test.ts: 65 passing tests.
• Ran bun --cwd=apps/web run build: production Next.js build completed successfully on the rebased branch.
• Verified there were no remaining conflict markers in tracked project files before continuing the rebase.

Issues, Limitations, and Mitigations

• The conflict resolution was test-only, so no additional UI screenshots or browser checks were needed for this turn.
• The branch history changed because the fix was done via rebase, which requires pushing the updated branch tip back to the PR.

Follow-up Work

No further follow-up was identified from this conflict resolution. The branch is ready for PR mergeability to be re-evaluated after push.
