Iris

The app is shot through a camera lens: an iris closes on every downbeat and opens on a new screen, so the iris is the transition.

A dark void dominated by a huge brushed-metal camera aperture: nine lacquered blades, a ticked rim ring and four rings stepping back like a lens barrel, with a deep well behind and a hard pinpoint of light burning through when the blades are shut. Five 6 s beats at 120 bpm across 30 s, each opening on a glide or push and slamming shut on the downbeat before a slow pull-back finale.

    THE IDEA. The app is shot through a lens. A camera aperture the size of a table — a brushed
    graphite face plate, nine black-lacquer blades, a stack of concentric rings stepping back like
    a lens barrel — stands in front of an iPhone. The film opens on the iris CLOSED with the brand
    colour burning through the pinhole; it irises open and the app is there. Every feature beat is
    a blink: the iris slams shut on the downbeat (a click), the camera has moved, the iris opens,
    and the screen behind it has changed. The iris IS the transition. At the end the whole iris
    slides back past the phone and stays open behind it as a halo, next to the app's name.

    THE WORLD. A void (graphite-to-black gradient). The aperture: a 660 mm graphite face plate with
    a 105 mm aperture and two engraved grooves, an accent lip ring at the aperture, a rim ring with
    48 index ticks (it turns a notch every time the iris closes), four rings stepping back
    (r 366 / 388 / 406 / 422), a black obsidian disc behind the phone. Nine blades (extruded,
    alternating two lacquer tones, a 3° cone tilt so each catches the key differently) slide
    radially behind the plate while the blade set turns 30° — a real iris's pinwheel close.
    Rule: the phone never translates (a device position channel blanks the screen); it only turns.
    The iris moves only in the end card, and only after it is fully open (aperture 105 > phone 88).

    BEATS (music 120 BPM: a beat 0.5 s, a bar 2 s; every cut on a bar line, every iris slam on a cut)
      a1-hook     0–6     straight on, wide: iris closed, amber burning through the pinhole; the iris
                          opens 1.0–2.2 on scr-home while the camera glides in; slams shut 5.3→6.0
      a2-f1       6–12    STRAIGHT ON, phone right of frame: opens on scr-f1; "Plan it in / one line."
                          engraved on the plate; the plan types into slot-input (typewriter), the
                          parsed plan (slot-hero) lands, slot-cta dips; slams shut
      a3-f2       12–18   THROUGH THE BLADES: from high right the iris opens only halfway, the phone
                          seen through the polygon; it opens fully as the lens pushes through the
                          aperture into the ULTRA close-up on slot-hero ("86% on track", yaw 52–56°,
                          fill 165–175, dof 40/12); pulls back out; slams shut
      a4-f3       18–24   SIDE, from the left (≈50°): the iris opens on a bare ground (lyr-bg); the
                          other three layers fly in out of the lens and stack in front of the glass
                          (+22/+44/+66), then pack home magnetically (UI-ASSEMBLE); caption 3; shut
      a5-end      24–30   the iris opens wide and slides back past the phone, shrinking into a halo
                          behind it; "Lumen" + tagline rise in the clear left half; scr-home

    TEMPLATE SLOTS — re-skin by editing only these (everything else stays):
      BRAND    text3d#e-name (a5-end, the app name) · text3d#e-tag (a5-end, the tagline).
               Keep: font=poppins weight=700, sizes, align=left anchor=baseline; a longer name → smaller
               size so it ends left of x = −250 (the halo's edge).
      ACCENT   one colour in exactly three places (all at the top of this file):
                 1 material  m-accent        (aperture lip ring, the pinhole glow disc)
                 2 light     accent-rim      (template t-lights, the back-right rim on the rings)
                 3 light     accent-glow     (a1-hook only, the pool round the pinhole)
