Create a 16:9 monochrome 2D storyboard line-sketch sheet for a winter queen forging and charging a katana through ritual dance; show its attached horizon extension, and do not render bracketed labels.
[HEADER]
Minimal header, crisp typography, one thin rule; show only:
"Crown of Frost"
"Forge, gather, swing, extend"
[BOARD]
Balanced sheet with 11 near-equal 16:9 landscape panels, clear gutters, natural P## order, and a centered incomplete last row.
Headers use `P## / camera angle / short beat`; one frozen beat each, count and order above packing.
[STYLE]
Clean monochrome 2D storyboard line sketch on white paper: sparse single-pass graphite-gray contours, simplified featureless figures, minimal construction marks, essential set geometry.
No dense/repeated lines, facial/anatomy/clothing/surface detail, fills, wash, hatching, shading, shadows, ambient occlusion, color, texture, 3D/clay volume, or finished rendering.
[REFERENCES]
Image A controls only Yuki's gross build, hair mass, crown, and layered feather silhouette.
[CONTINUITY]
Keep Yuki's crown, braid, slim silhouette and train fixed; no katana P01, right-hand hilt P02, complete katana P03-P11.
All ritual contours stay blade-bound; the P10-P11 extension is rooted only screen-right, none behind Yuki.
[RULES]
Only two header lines and panel headers are visible; no panel text, arrows, icons, insets, duplicates, ghost poses, or detached object-like effect marks.
[BEATS]
Draw one storyboard panel per visual BEAT:
BEATS:
P01 / FRONTAL ECU / pressure held: Eye-level frontal ECU, hidden horizon; Yuki's face fills frame, both hands outside and no sword visible.
P02 / HAND ECU / form begins: Side hand ECU, no horizon; Yuki's open right palm frames one half-formed hilt and guard, attached contours marking unfinished edges.
P03 / BLADE ECU / sword complete: Blade-axis ECU, no horizon, guard near and tip far; Yuki grips one complete katana, residual contours fixed to its new edge.
P04 / LOW FRONT 3Q / current caught: Knee-height front three-quarter FS pitched up, low horizon; Yuki holds a deep side bend, katana diagonal low-left, contours converging on its edge.
P05 / FRONT 3Q / current folded: Waist-height front three-quarter FS, level horizon; Yuki counter-arches with katana high screen-right above one shoulder, contours layered along the blade.
P06 / LOW PROFILE / charge carried: Knee-height profile FS pitched up, low horizon and spires; Yuki holds a deep backbend, katana behind her shoulder line, contours clinging to its arc.
P07 / PROFILE FS / power compressed: Waist-height profile FS, level horizon; Yuki plants a weighted side step, torso contracted, katana across her front toward screen-right.
P08 / BLADE ECU / edge saturated: Side blade-axis ECU, no horizon, guard near and tip far; one dense unbroken contour skin hugs the entire katana edge.
P09 / LOW REAR 3Q / blade loaded: Ground rear three-quarter MLS pitched up, low horizon; Yuki faces right, katana reaches screen-left into near foreground, oversized blade beside the frame edge.
P10 / GROUND PROFILE / edge lengthens: Ground profile WS, low horizon and near ice planes converge screen-right; Yuki holds a rightward swing apex, katana near foreground, rooted extension open from its outer edge.
P11 / HIGH PROFILE / scale expands: Raised profile EWS pitched down, lake top plane and foreground spire visible; Yuki is tiny lower-left, continuous extension links katana to a vast front filling the right two-thirds beyond the horizon.
