Velvet Rot

Bug-fix and polish pass after the first Early Access feedback wave. ## Fixed - Fixed location lockouts so incomplete maps or missing room-pin data do not block visiting a location. - Fixed Dylan's Cedar Terrace route pin by assigning the study group scene to `Dylan's Room`. - Fixed phone texts rendering out of order by sorting phone scenes more consistently. - Fixed scene costs still showing as `???` in some cases. Costs should now always be visible. - Fixed missing image references showing broken browser image icons by adding safer image rendering across scene cards, scene images, phone images, and VN mode. - Fixed several Noah farm choice cards using the wrong domain tint when mixed-domain reward splits rounded awkwardly. - Fixed a rewind exploit on farm interrupt scenes where re-choosing after a rewind could stack rewards repeatedly. - Fixed a Noah farm basement line rendering with the wrong presentation/speaker attribution. - Fixed farm scenes with interrupt-based rewards not showing reward info on the scene card. ## UI / UX - Simplified location maps so they use one room pin per room/location instead of stacking multiple scene pins on top of each other. - Moved scene differentiation into the side panel, with character-based filtering for scenes in the selected room. - Added fallbacks for locations that are still missing a proper detailed map. - Tightened VN layout so it fits the screen better and wastes less vertical space. - Cost-locked scenes now have a distinct appearance on location maps, separate from already-seen scenes.
