//
// Techniques used here:
// - glyph positions are computed like the browser's layoutText (full-width glyphs = 1 em, latin estimated), so streams /
//   shadows / bands line up with the AE text (exact for Japanese).
// - "one glyph per line" text layers (lb1_glyphs) hold many freely placed glyphs in ONE editable layer: every line is
//   centre-justified, so glyph i sits at (0, i*LD) no matter how wide it is; a Position animator moves it anywhere.
// - moving plates / strings / bubbles are shape layers; the lyric glyph that rides on them is parented (setParentWithJump)
//   so the cut's enter / hold / exit expressions stay untouched on the text layer.

var LB1_CY = 0.38;     // glyph centre above the baseline (em) \u2014 CJK em box

// Techniques used here:
// - print objects that move as a whole (pages, plaques, cassettes, polaroids, the spinning newspaper) are one shape layer
//   (or a null) whose transform is driven by expressions; the texts that ride on them are parented to it, so the cut's
//   enter / hold / exit expressions on the lyric stay untouched.
// - secondary copy (body rows, greeked columns, leaders, crop marks) are text / shape layers faded or trimmed in with
//   expressions on `time` (0 = cut start); lc1_H(ctx) = jzTH(ctx) (DUR IN OS OD PO K + easings) + ioc (inOutCubic).
// - glyph positions of the lyric (footnote marks, proofreading marks) are estimated like the browser's layoutText
//   (exact for full-width Japanese) and scaled to the AE text layer's measured width.

// - paper objects are shape layers ("rigs") whose transform expressions carry the object's motion (fly in, swing, tear\u2026);
//   their text layers are parented to the rig, so the lyric keeps the cut's enter / hold / exit on its own layer.
// - glyph positions are estimated like the browser's layoutText (full-width glyphs = 1 em), used for fitting and placing.
// - vertical columns (right \u2192 left) = one text layer with one glyph per line + a per-glyph Position animator (lc2_V).
// - many small labels (zip digits, dates, station codes \u2026) = one text layer, one label per line, moved per glyph (lc2_multi).
// - clip windows that open (folded paper, unrolling scroll) = a thin static rectangle mask + animated Mask Expansion.
// - dotted lines / perforations = stroke with dash 0 and round caps.

// Techniques used here (no 3D layers \u2014 the faux 3D is done with 2D affine maps, as in the browser):
// - an affine map M = [a, b, c, d, e, f] (x' = a*x + c*y + e, y' = b*x + d*y + f) is split by aff() in the expressions into
//   Rotation * Skew * Scale: shape groups take it as their group transform, a text layer through a Transform effect.
// - deforming quads (cloth strips, ribbon segments) are pairs of triangles: a 100 px unit triangle mapped by its group
//   transform. All triangles of one surface live in sub-groups of ONE group with ONE fill, so they fill as a union (no seams).
// - "glyph layers": one glyph per line, anchor = position (layer space == comp space); per-glyph animators move / turn /
//   scale / hide each glyph, so many freely placed glyphs stay ONE editable text layer.
// - moving objects that carry a lyric glyph are separate shape layers and the text is parented to them, so the cut's
//   enter / hold / exit expressions on the text layer stay untouched.

// Techniques used here:
// - clipped copies of the lyric (puzzle pieces, kaleidoscope wedges, blind slats, stacked slices, mosaic) are ONE precomp that
//   holds the plate + the lyric (still one editable text layer, with its enter / hold / exit), used several times with masks.
// - projected / folding polygons (walls, paper flaps) are fixed unit shapes mapped by the shape group transform
//   (position + rotation + skew + scale = any 2D affine map), driven by expressions: no animated paths needed.
// - pattern-filled lyrics (maskReveal, halftoneBig) use the lyric as an alpha track matte for a pattern layer.

// - helper graphics the browser draws with ghost off are kept out of the tinted ghosts (jzNoGhost).
