sig-select sprint: SigReservation model + sig_reserve view (OK/NVM hold); full sig-select.js rewrite with stage preview, WS hover cursors, reservation lock (must NVM before OK-ing another card — enforced server-side 409 + JS guard); sizeSigModal() + sizeSigCard() in room.js (JS-based card sizing avoids libsass cqw/cqh limitation); stat block hidden until OK pressed; mobile touch: dismiss stage on outside-grid tap when unfocused; 17 IT + Jasmine specs
