0.7.6

An adoption-feedback release: everything here came from tosijs-3d-ensemble hitting it for real.

Fixed

• The icon LANGUAGE now works on the texture path (#54). icon-data stores every value with a trailing space, and a redirect is re-parsed as a name where that space is fatal — so parseStyleSuffixes('cornerUpRight0f ') returned null while the trimmed form resolves. Every mirrored icon failed to resolve, which is the whole left-facing set (they are all stored as <rightVariant>0f), on both the DOM and texture paths.

  iconGlyph also computed the composed style and then discarded it with a warning; it now applies it as an SVG transform. So a plain NAME carries the whole language everywhere — cornerUpLeft, chevron270r — and the KeyDef.iconRotate/iconFlipX workaround is deleted rather than copied into IconGridItem.

• iconExists(name) is exported, because the alternative is guessing: name in iconData says no to every composed name, and inspecting the stored value says no to every mirror.

• b3d-shadows no longer writes receiveShadows on instanced meshes (#53) — Babylon warns once per instance and ensemble measured ~10,000 messages on one load. The write was already a no-op (an instance takes the flag from its source), so nothing that received shadows before stops now.

• You can swim up again. Head depth was derived twice and the two disagreed: the up-thrust gate included bodyBottom, the up-AIM clamp did not. A swim pose puts the root at the waterline with the body below it, so the aim clamp thought the head was a body-length shallower than it was and clamped upward aim to nothing — you could push up but not aim up.

• The keyboard works with ONE presentation. useDomLayer was opt-in, so a flat-only consumer got no keyboard at all on a height: 'fit' panel and a cropped one on a tall panel. The DOM layer now installs itself when the panel is on the page.

• The sky advances by measured time, not by the interval it asked for — a backgrounded tab throttles timers, so the day cycle ran ~10x slow and never caught up.

Changed

• Underwater fog eases toward the surface rather than being full-strength until the crossing band.
• Console hygiene: icon warnings fire once per problem rather than once per draw (they run from drawing code), demos report on the page instead of logging, and our own deprecated tosijs usages are gone — elementCreator({tag}) → static preferredTagName, static styleSpec → shadowStyleSpec.
• b3d-physics imports PhysicsViewer from the barrel rather than mixing a deep path with it in the same module — the classic route to two Babylon module instances in a consumer's bundle.
