CSS only (native off). No glassd: Steam's keyboard background is recoloured as WN §8.4's degraded glass (tint .84, a sheen from above, the edge arc and lobe, a dark inner edge). Honest tinted glass, not frost of the room.

Secret field, masked echo. The echo shows the field's name and dots, never characters: type=password, one-time-code and PIN fields, and every field of a password, PIN or Steam Guard dialog. Enter reads “Done”.

Same layout as native. The echo sits on top and the key block moves down 41 kb px (hit areas move with their keys). With an IME, emoji or Steam's own text row the keys stay put and the echo uses the bottom band (controls-keyboard-states).
