Smoke-test report: the Achievements list isn't scrollable. With 19 achievements the panel overflows the modal at the 800x600 minimum window and the bottom rows are clipped. The same problem applies to several other modals whose content has grown over the v0.13–v0.15 rounds. Mirrors the existing SettingsPanelScrollable pattern from settings_plugin: each modal's body Node gets Overflow::scroll_y() plus a max_height (Val::Vh(70.0) for most, Val::Vh(50.0) for the leaderboard's variable-length ranking section), a marker component so the scroll system can find it, and a sibling system that routes MouseWheel events into the body's ScrollPosition. Five modals fixed: - Achievements: 19 rows clearly overflow; AchievementsScrollable + scroll_achievements_panel. - Help: ~28 reference rows overflow at 800x600; HelpScrollable + scroll_help_panel. - Stats: 8-cell primary grid + per-mode bests + progression + weekly goals + unlocks + Time Attack readout + replay caption is enough content to overflow once the player has any progress; StatsScrollable + scroll_stats_panel. - Profile: Sync + Progression + 14-day calendar + up to 18 unlocked achievements + Stats summary overflows once a few achievements unlock; ProfileScrollable + scroll_profile_panel. - Leaderboard: 10-row cap is at the edge of overflow on 800x600 with long display names; LeaderboardScrollable + scroll_leaderboard_panel (max_height = 50vh — the ranking section is the only variable-length part). Home modal NOT scrolled — five mode cards plus a Cancel button were sized to fit at 800x600 by design and adding scroll there would clutter the launcher. Five new tests pin the contract: each modal's body has the scrollable marker, a non-default max_height, and Overflow::scroll_y. Defer-list (small UX nits surfaced during the sweep, not fixed here): - Modal close-on-click-outside is missing across the board; would need Interaction on ModalScrim in ui_modal. - ModalButton hover doesn't set a pointer cursor. - Tab focus on modal open is initialised on the next frame instead of the same frame; first Tab press selects rather than focus already being on the primary. These are bigger touches than the scroll fix and don't fit a 30-LOC budget; surfacing for a follow-up round. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
