User dev-server walkthrough surfaced 4 functional UX gaps beneath the verifier's
24/24 structural PASS:
G1 (blocking) — no global page CSS → white halo around #1a1a1a canvas
G2 (blocking) — no first-run prompt after Begin → player confused
(A Dark Room rule needs the canonical first-prompt)
G3 (high) — tile outlines too dim → grid reads as 'gray check block'
G4 (medium) — gate visual at canvas (880, 384) reads as stray rectangle
Phase 3 watercolor deferral preserved — every fix uses Phaser primitives or
one CSS file, not painted assets. STATE.md → status: gaps_found.
