An 8-second text-only wordmark reveal in HyperFrames (1280x720, 240 frames at 30fps). House style: near-black #0a0a0a background, white type, ONE orange accent #ff5c1a, Arial/Helvetica bold, no webfonts. No icon, no mark, no shape of any kind — the word IS the logo. Letters land one by one, a single orange rule draws underneath, then the tagline lands. Fictional brand only — never a real company's wordmark or name. No gradients, no stock photos, no letter-spacing animation.

<structure>
Seconds 0.0-0.7 — Kicker "WORDMARK REVEAL — Halcyon" in orange, top left.
Seconds 0.7-1.75 — The wordmark "Halcyon" lands letter by letter, large, centred, wide tracking, each letter rising 50px into place with a 0.12s stagger.
Seconds 1.9-2.6 — A single orange rule draws left to right beneath the wordmark (scaleX 0 to 1, left origin).
Seconds 2.9-8.0 — Tagline "Sound, made visible." fades in under the rule; a small grey footer line names the brand as fictional and the film as a prompt test.

<build>
One HTML composition with a seek-driven GSAP timeline. Letters are separate spans animated on opacity and y only (never left/width tweens — they break under seek capture). The rule is a plain div animated on scaleX with transform-origin left centre. Size the wordmark to the frame: 7 letters at 120px with 18px tracking fit a 1280px canvas with margins; longer names must shrink the size, never the tracking, and never wrap to two lines.

<gotchas>
- Text-only is the whole brief: adding an icon, dot or shape turns this entry into a different format. If the brand needs a mark, use the minimal-line or monogram prompt instead.
- Never animate letter-spacing: it reflows every letter mid-stagger and looks like a glitch under seek capture.
- The rule must sit exactly under the wordmark and be shorter than it — a rule wider than the word looks like an underline error.
- The kicker fades out in the last 0.6s so the final frame is just wordmark, rule and tagline.
- Check the final frame as a still: no letter clipped, rule centred, tagline clear of the footer line.

Before you finish: step through the timeline at five points and fix anything that overlaps, clips the frame, or drifts off the beat grid.
