# 15 Voyage, look 2 — report
|
||||
|
||||
Status: **done** (not committed). Built from `15-voyage-look2-brief.md`, starting from a copy of 14.
|
||||
|
||||
## What was built
|
||||
|
||||
`src/mockups/15-voyage-look2/` is 14's five-beat voyage with its side panel, tabs, placeholders and URL
|
||||
params (`?beat=` `?t=` `?play=` `?tab=` `?panel=0`). New params: **`?paths=a|b|c`** (default `a`) and
|
||||
**`?motif=<id>`** (starts with that motif highlighted).
|
||||
|
||||
1. **Look 2 only.** The look toggle, look 3's palette, sail and panel code and the `Look` type are gone.
|
||||
Look 2's colours are unchanged: teal and cream sea, cream sky, terracotta frieze, bright motif colours.
|
||||
2. **Look 3's cohesion, on look 2's colours.**
|
||||
- **One ornament.** The frieze's meander key band, drawn as a strip between glaze rules, runs along
|
||||
the top of the panel (18px), the caption card and the step bar or timeline (12–14px). It is the
|
||||
same tile as in the frieze.
|
||||
- **One type pairing.** All labels use the frieze inscriptions' style: Cormorant, capitals, wide
|
||||
tracking. That covers the caption eyebrow, the panel eyebrow, tabs, fact labels, beat labels,
|
||||
"Paths", strip headings, fan-work types and the B labels. Titles stay in Cormorant and body text in
|
||||
Inter.
|
||||
- **One accent pair.** Terracotta and glaze black replace 14's rhumb-red. Track badges and the
|
||||
current beat are terracotta discs with black numerals, as on the frieze. Play and Back are black
|
||||
pills. Cards have black 2px rules. The current tab has a terracotta tongue. The footer is glaze with
|
||||
a terracotta rule. The vellum roller edge is replaced by a black rule, so the panel reads as the
|
||||
same book as the frieze.
|
||||
- **Fitted frieze.** The viewBox is now cropped to the band, and the band sits in a box between the
|
||||
caption and the HUD. Two registers fill the height: a **palmette chain** above (a vase neck) and a
|
||||
**running-wave scroll** under the ground line. The horizon sync and the curtain drop were rewritten
|
||||
for the new box. The morph still starts on the painted ground line (`-morph.png`).
|
||||
- **Sea.** The filled crest patches (14's "lily pads") are gone. The sea is now two flat swell bands
|
||||
plus thin cream wave strokes on the upper swells, which thin out with distance.
|
||||
- **Giant.** The outline hulls are half as thick (0.32 → 0.15). The giant is scaled 0.8 → 0.72, so the
|
||||
club stays well inside the frame. The flock's outlines are halved too.
|
||||
3. **Paths out in the open.** "Paths A · B · C" sits in the HUD with a short name (In the panel / In the
|
||||
world / Timeline). In all three modes, the current song's motifs show without any click. **One pick
|
||||
highlights everywhere**: the pinned strip, the Paths tab (buttons and vertical strip), lyrics (the
|
||||
matching parts light up, the others dim, and the chips are buttons), frieze threads, 3D ribbons and
|
||||
their labels, and the timeline. The pick is kept across songs when the new song has that motif, and
|
||||
is mirrored in `?motif=`. The Paths tab stays as the full detail view.
|
||||
- **A. Pinned strip** (`threads.ts` `hStrip`, about 150px). It sits between the song header and the
|
||||
tabs, whatever tab is open. All 10 songs are knots on a dashed course, numbered, with saga ticks
|
||||
and a terracotta "here" column. A small ship with "you are here" **sails between songs as the beats
|
||||
play**. One soft thread per motif, knotted where it plays (12's style). The motif names are buttons
|
||||
with a from/returns tooltip.
|
||||
- **B. Threads in the world** (`ribbons.ts`). Every song has a fixed place on the route: two behind
|
||||
the start, Full Speed Ahead at the start, Polyphemus at the anchorage, Survive at the cave mouth,
|
||||
and the rest beyond the island. Each motif is a flat ribbon with a black edge that rides the waves.
|
||||
It is **solid behind the ship and dashed ahead**, with open-ring knots. Each ribbon has a floating
|
||||
vellum label on its next knot ahead ("POLYPHEMUS · next: 7. Survive"), and labels stack when they
|
||||
would overlap. Ribbons fade out near the camera so they don't become roads. In the cave, ribbons run
|
||||
along the floor between the flock and the giant. In the frieze beats, the wave-scroll register
|
||||
becomes the **thread register**: ink-edged threads in the bright colours, knotted under each painted
|
||||
song, running off the band where the motif continues, with names on the left (clickable).
|
||||
- **C. Timeline at the bottom.** The HUD becomes a full-width vellum timeline. Its top row holds Play,
|
||||
the steps, the beats and the paths toggle. Below are all songs as stops with titles, saga names,
|
||||
the "here" column, the sailing ship with "you are here", and the motif threads underneath. The
|
||||
frieze box shrinks so the band still fits above it.
|
||||
|
||||
Files: `main.ts` (beats, paths mode, motif pick, B labels, C timeline, fitted frieze), `panel.ts`,
|
||||
`threads.ts` (new: shared thread data and the horizontal strip), `ribbons.ts` (new: 3D ribbons),
|
||||
`scene.ts` (one palette, sea strokes, thinner outlines, ribbons and label projection), `frieze.ts`
|
||||
(cropped viewBox, chain and wave or thread registers, tighter mouth mask), `figures.ts`, `chart.ts`,
|
||||
`fanworks.ts` (copied), `style.css`.

||||

||||

The credits footer is fully visible in every one.
|
||||
|
||||
## What works
|
||||
|
||||
- **Cohesion.** The meander strip, the capitals labels and the terracotta/black accents tie the
|
||||
caption, HUD and panel to the frieze, and the sea and sky keep look 2's pop. It now reads as one site.
|
||||
- **The frieze fills the stage.** The band sits between the caption and the HUD with only a small
|
||||
margin of glaze (`-beat1`, `-beat4`). The new registers look native to the vase.
|
||||
- **The sea** reads as drawn strokes, not pads. The giant is lighter and fully in frame.
|
||||
- **A** is always visible without changing the panel's job, and the sailing ship makes it feel alive.
|
||||
- **B** is the most striking: the threads literally run ahead of the ship to the cave mouth
|
||||
(`-paths-b`). In the frieze, the thread register is a natural vase band (`-beat1-paths-b`).
|
||||
- **C** is the clearest overview. It is the user's "big horizontal line", with every song titled.
|
||||
- Checked: `bun test` (50 pass), `bun run typecheck`, and a production build to the scratchpad.
|
||||
|
||||
## What doesn't, or is rough
|
||||
|
||||
- **B labels on the island** can stack over the cave mouth, as Odysseus and Polyphemus both return in
|
||||
Survive (`-paths-b`). They are readable, but the leader line of the upper label points at nothing.
|
||||
- **B ribbons behind the ship** sweep towards the camera at the lower left in beat 2. They now fade, but
|
||||
still cross under the HUD. The far ribbons (tracks 8–10, beyond the island) are only small dashes.
|
||||
- **B's frieze labels** are small (about 12px on screen at this stage width).
|
||||
- **A at 372px is dense.** The 10 knots are about 22px apart, so the numbers carry the meaning and song
|
||||
titles appear only in tooltips. "Warrior of the Mind" just fits the label column.
|
||||
- **C costs about 220px of stage.** The landfall and cave are framed higher, and in the cave the flock
|
||||
sits behind the timeline (`-beat5-paths-c`).
|
||||
- The morph frame shows a large flat sun with a ring. This is 14's camera at horizon lock, not changed.
|
||||
- Play timing was not checked in a live browser (headless virtual time, same caveat as 13 and 14).
|
||||
Desktop 1440×900 only.
|
||||
|
||||
## Paths A / B / C, honestly
|
||||
|
||||
**A (pinned strip)** is the safest. It is always there and compact, it keeps the stage clean, and the
|
||||
sailing ship makes "you are here" concrete. But it is small and abstract: numbers, not names, in a busy
|
||||
panel. It fixes "too hidden" without making paths feel like part of the voyage.
|
||||
|
||||
**B (threads in the world)** is the most "EPIC". The motifs become something the ship sails along, and
|
||||
you see a theme run ahead into the Cyclops' cave before the song gets there. The frieze version is
|
||||
lovely. The costs: it depends on camera framing (labels stack, ribbons near the camera need fading),
|
||||
and it shows only the current song's motifs, with no overview of the whole voyage. It is the hardest
|
||||
to build well for every landing.
|
||||
|
||||
**C (timeline at the bottom)** is the clearest. Every song is named, the threads are long enough to
|
||||
read as journeys, and the step controls sit with it naturally. It costs stage height, and the
|
||||
interface feels more like a tool and less like a picture.
|
||||
|
||||
My read: **C as the home for paths, with B's ribbons as an optional flourish in the 3D** (the frieze
|
||||
thread register in particular is cheap and beautiful). A works as a fallback when the panel is the
|
||||
main surface, for example on smaller screens. Each needs one more pass: C could collapse to a slim
|
||||
course line while the 3D plays, and B labels need smarter placement.
