[1.2.2]

SingleSlotReelsSpinSystem settings now expose slotStopDelay to pause between individual slot stops within a column while reelStopDelay continues to pace the first slot in each column, enabling layered timing without manual timers.
HoldAndWin stories expose slotStopDelay as a dedicated control to preview staggered slot timing.
HoldAndWin stories configure fractional steps for all numeric controls to enable fine-grained tuning during demos.
Added a stub MaskingSystem and wired it into Reels spin stories to prepare future masking orchestration work.
Introduced BlurSymbolsSystem to centralise blur orchestration for reels symbols.
Added dedicated Storybook demos for MaskingSystem and BlurSymbolsSystem, now mirroring the reel spin setup while piping Storybook controls through each system's setSettings method for live configuration tweaks.

Reels reel states no longer toggle blur directly; ReelsSpinSystem marks blur intent while BlurSymbolsSystem applies filters.
BlurSymbolsSystem removes cached filter areas, zeroes padding, and supports runtime velocity/kernel/offset configuration through setSettings.
MaskingSystem exposes an enabled flag so Storybook demos and games can disable masking without removing the system from st ates.

SingleSlotReelsSpinSystem trims transient slot symbols and collapses each delayed reel to its landed symbol so duplicates cannot appear when slotStopDelay is enabled.
Column stop scheduling now respects reelStopDelay for the first slot in each column even while previous columns finish their queued slots, keeping staggered visuals aligned across reels.
Reel symbols remain visible when blur and masking are enabled together by removing conflicting bitmap caching from the blur toggle.
Motion blur applied to masked reel symbols now clips to the mask bounds so blur streaks no longer extend beyond the masked area.

Story: DoubleHoldAndWinStory showing two HoldAndWinMachine instances stacked vertically, each with different initMap/screenMap.

HoldAndWin stories: scaled all MachineContainer instances to 0.5 (half size). In DoubleHoldAndWinStory both containers are scaled; spacing uses containerTop.height and respects scale. centerView alignment remains correct.

Introduced HoldAndWin machine scaffold and Storybook story (features/HoldAndWin).
Single-slot reels support:
- SingleSlotReelsSpinSystem
- SingleSlotReel
Hold-and-win demo assets and manifest:
- configs/slotMachine.json
- symbols, anticipation, winline assets, bitmap fonts, textures
Auto-trigger spin in HoldAndWin story with generated screenMap and applied spin settings.

ReelsSpinSystem: support preventReelsSpin map to disable start/stop for selected reels; skip prevented reels in the spin flow.
ReelsMachine: integrate new maps/behavior for single-slot reels and preventReelsSpin handling.
Reel: adjustments to support single-slot behavior.
createScreenInputMap: generate maps aligned with the new HoldAndWin config.
SlotMachineConfig: extended with properties required by HoldAndWin and updated spinning behavior.
index.ts: export newly added modules.
ReelsSpinSystem story: updated with example demonstrating disabled first/last reels.
