Compact tournament header — Tournament info (type, players, time control, round) is now displayed inline next to the title, reducing vertical space by ~100px
Breadcrumb stepper — The 4-step progress bar has been replaced with a compact breadcrumb: ✓ Registration → ✓ Start → Round 1/5 → End
Inline visibility controls — Tournament visibility and share links are now a single compact row with “Copy link” buttons instead of full-width input fields
Round navigation via dropdown — “Round 1 of 5” now includes an inline <select> to jump between rounds instantly, replacing the numbered circles
Keyboard hint updated — Quick entry instructions now mention clicking the board number (more precise) and forfeit via dropdown menu
Unified color palette — All action buttons use a single primary blue (#2563eb). Removed inconsistent greens, oranges, and gradients across the interface
Mobile-optimized tabs — Horizontally scrollable tabs with inline counts instead of badge circles, ensuring all tab names remain fully readable
Mobile pairings layout — Save bar stays sticky at the bottom of the screen; “Generate next round” button appears immediately after saving all results

Added

Dismissible demo banner — Demo tournament banner can now be closed with × (remembered per session)
Mobile bye management hint — An informational message about bye/withdrawal assignment appears above the Player Management section on mobile

Removed

“Ready to start!” green box — Replaced with a compact neutral row showing player count, round count, and generate button inline
