game-views: forthcoming watermark no-overlap; reelhouse term; Text swipe-machine DOWN-hold-OVER + Jasmine-tested nav

Three things on the carousel:

- CHAT/PULSE stub: the shared [Feature forthcoming] partial centres itself absolutely, landing on top of the flex-centred watermark icon. Override it to flow (position:static) inside .room-view-stub so the icon keeps the top slot and the label rests below — FT asserts the icon's bottom clears the label's top (no clip).
- Adopt 'reelhouse' as the collective term for the fivefold applet-scroll carousel (class on #id_room_views + comments).
- Text sub-btn swipe machine: when already reel'd down onto the reelhouse, slide straight over to POST (plain goToView); when starting up in the room (the hex), run smooth DOWN to the reelhouse, HOLD 0.5s, then OVER to POST unless already there — the hold beats the two motions apart (DOWN-then-OVER, never diagonal).

Test rework: the from-hex OVER beat is a DELAYED (post-descent + hold) programmatic scroll, which headless Selenium drops/resets (works fine in a real browser), so the end-to-end land-on-POST can't be FT'd. Split it: the FT now asserts the reliable DESCENT beat (Text from the hex reveals the reelhouse + icon strip), and a new Jasmine swipe-machine spec pins the nav DECISION (from hex → POST after the descent+hold; inactive btn → no-op) against a fixture + mocked clock. room-views.js exposes init() so the spec can bind to the fixture.

Verified: 8 carousel FTs + Jasmine (atlas merge + swipe machine) green.
