First slice of the move-log mockup at
docs/ui-mockups/replay-overlay-mobile.html § "Move Log Card".
Adds a separate root UI entity anchored to the viewport's bottom
edge (sibling-of-banner pattern, mirrors ReplayFloatingProgressChip
lifecycle) carrying a `▌ MOVE LOG · N/M` header plus a single row
showing the most-recently-applied move.
Subsequent commits in this multi-session arc add prev/next rows,
active-row highlight, and auto-scroll on cursor advance. Splitting
the work at "panel + active row only" lands the structural piece
(panel exists, lifecycle works, format helpers proven) before
tackling the harder questions about rendering un-applied future
moves and scrolling.
Position decision: bottom-of-viewport (matches mockup), separate
root entity from the 92 px top banner. Keeps the banner from
growing further into a top-heavy 170+ px strip; the
top-status + bottom-info paradigm reads as vim/IDE-style buffer
chrome that players intuitively scan.
Four pure helpers handle the formatting:
- format_pile(p) → lowercase, 1-indexed display string
("foundation 3" rather than enum's 0-indexed Foundation(2))
- format_move_body(m) → "{from} → {to}" or "stock cycle"
- format_move_log_header(state) → "▌ MOVE LOG · N/M",
"▌ MOVE LOG · COMPLETE" for `Completed`, empty for `Inactive`
- format_active_move_row(state) → "{cursor} │ {body}" with
1-based cursor for player display, empty at cursor=0
Two per-frame update systems (update_move_log_header,
update_move_log_active_row) repaint the texts on resource change
with the standard early-exit-on-no-change idiom.
Despawn handling: react_to_state_change gains a third query for
ReplayOverlayMoveLogPanel entities and despawns them on
Playing → Inactive alongside the banner root and floating chip.
Panel border carries HighContrastBorder so the 1 px top edge
bumps under HC mode — same pattern as the keybind footer.
8 new tests:
- format_pile pile-name + 1-index pinning
- format_move_body both-variant pinning
- format_move_log_header three-state coverage
- format_active_move_row cursor=0 vs cursor>0
- move_log_panel spawn cardinality (exactly one)
- move_log_panel header paints helper string at spawn
- move_log_active_row repaints on cursor advance
- move_log_panel despawn parity with overlay tree
Tests: 1254 → 1262. Clippy clean.
