CANVAS1920 × 1080, 16:9, alwaysEvery scene, every source, every export. 1280×720 only if upload is the constraint — never a non-16:9 canvas.
TITLE-SAFEInner 90% — all text lives hereThe solid brand rule. Nothing readable crosses it: platform chrome, chat panels and phone notches eat the outer band.
ACTION-SAFEInner 93% — dashedGraphics may touch it; only full-bleed backgrounds and the top accent bar go past.
GRID12 columns × 8 rowsEvery zone snaps to it. A panel that starts at a non-column edge is the first sign a scene was improvised.
01 KICKERTop-left, mono, uppercase// LIVE SESSION 04 — the same eyebrow every thumbnail uses. Names the series, never the mood.
02 STAGEThe teaching surfaceScreen, slides or camera. It is the only zone allowed to change between scenes; everything else stays nailed down.
04 CAMBottom-right, 16:9, 18–22% widthNever over the slide's content column. Same corner all stream — moving it costs the viewer a re-scan every time.
07 MARKLogo watermark, bottom-right, 55–65% opacityAlways present, never animated after the intro. It is the frame's signature, not an element of the layout.
