Scapeso|Sound Mixing Platform

-Added: numbered drag handles next to each layer in the mixer. Long-press a number box and drag to reorder layers in the stack (replaces the previous up/down arrows). Volume % input beside the slider remains for precise volume entry. -Changed: raised the audio engine max layer count from 12 to 20 so it matches the mixer's 20-layer limit (adding a 13th+ layer previously failed in the audio manager even though the UI allowed it). -Added: soundscape names in Discover that don't fit on one line now slide (marquee) to reveal the full title, looping with a pause at the start and end; short titles that already fit are unaffected. -Fixed: cutting a layer sometimes trimmed a slightly different region than what was visually selected. A fast drag-then-cut could read a stale guide position instead of the one shown on screen; the cut now always uses the exact on-screen selection. -Fixed: layers from "My Sounds" (AI-generated) showing as the generic label "AI Sound" under a soundscape's name in the Library. They now show the sound's actual (possibly renamed) name. -Fixed: fade-in/fade-out glitching after shortening or lengthening a layer. Fade regions were left anchored to the layer's old (pre-trim) duration and could point past the new shorter length; they are now re-clamped to the layer's new duration whenever it changes. -Fixed/Stabilized: the UNDO button. It previously stored only a single last-action slot, which its own restore logic could overwrite mid-undo, so a second edit silently erased the first one's undo data and a failed restore could corrupt the next undo. Replaced with a proper 20-step undo history. UNDO now reliably covers: adding/removing a layer, trimming/cutting a layer and its fades, and layer position/volume changes. -Fixed: two layers using the same sound stacked on the same timeline position and rendered visually identical (both defaulted to the same color slot), making them look merged into one layer. Each new layer now gets a distinct timeline color so duplicate-sound layers stay visually distinguishable. -Fixed: detailed mixer's Simple/Detailed view toggle sometimes stopped responding ("tabs" not registering). The switch-view transition cleared its "switching" lock through a chain of animation-frame callbacks with no fallback; if that chain was ever interrupted (e.g. app backgrounded mid-switch), the toggle stayed disabled permanently. Added a safety timeout so the toggle always re-enables.
