The vertical capsule stack reached ~414pt up the screen, putting the top tabs out of thumb range. Replace it with 'Glass Bubbles': liquid-glass orbs that fan out from the FAB along a semicircular arc whose radius (~152pt, clamped to screen width) keeps every tab inside the natural thumb sweep from the bottom-center pivot. - Each bubble: ultraThinMaterial circle + top white gradient (specular light) + white 0.4 hairline + soft shadow; label with shadow below. Current tab rendered as green glass with white symbol. - Entrance: bubbles fly from the FAB to their arc slot while rotating -40deg -> 0 with a snappy spring (response 0.32, damping 0.72) and a per-item 0.03s stagger, like droplets bursting in sequence; collapse snaps back with no delay. All transform-only (offset/scale/opacity/ rotation) so no per-frame blur recomputation. - Struct renamed FloatingCapsuleMenu -> GlassBubbleMenu; storage key and NavStyle.radial rawValue unchanged for compatibility. - Settings copy updated: nav style now '글래스 버블 메뉴' with a description of the fan-out and one-handed reach; order editor renamed '버블 메뉴 순서' with left-to-right arc wording. Verified: clean rebuild (stale incremental link produced an old binary despite BUILD SUCCEEDED; wiped DerivedData), expanded-arc screenshot shows all 7 bubbles within thumb radius with legible labels, and the settings screen shows the new name/description.
