248 ANTHEMS · DALLAS ATHLETIC CLUB · EAST DALLAS
Sunday, 100°
01The design direction
Of the four Dallas courses, this one has the single best-documented event in the whole wave: the 45th PGA Championship, 18–21 July 1963. A 23-year-old Jack Nicklaus started the final round third, three shots behind Bruce Crampton, shot 68 against Crampton’s 74, and won by two over Dave Ragan — his first PGA title, the third of his eighteen majors, in heat over 100 °F, finishing with a Wanamaker Trophy so hot from the sun he needed towels to hold it.
But the concept is not the championship. It is the sequence: Ralph Plummer designed the course. Nicklaus won a major on it. Then Nicklaus came back and redrew it — the Blue in the mid-1980s, the Gold about five years after. Most architects never play the course they later alter; this one won a major on it first. That is genuinely unusual, and it is the spine of the page.

One support colour, per the brand system. The heat is carried by brass and by type weight — deliberately not by Accent Orange, which would have been the obvious move and would have spent the brand’s one loud colour on decoration. Orange appears exactly once on this site, on the pending-audio note, same as everywhere else in the series.
0204 Sunday, 100° — and why the line is straight
The signature plots the final round as strokes relative to Crampton, who is the flat zero line. Nicklaus enters at −3, exits at +3: a six-stroke swing, drawn at a declared 30 pixels per stroke. Ragan is marked at the finish, one above Crampton and two behind Nicklaus — second place, which is consistent with Crampton falling to third. A dashed vertical marks where the two lines cross.
Every one of those positions is derived in code from five published numbers: the three-shot overnight deficit, the two round scores, par, and the two-stroke winning margin. Three assertions check the arithmetic still holds — that the swing totals six, that Nicklaus finishes ahead of Crampton, and that Ragan lands between them. If someone later edits one figure and forgets another, the console says so rather than the chart quietly lying.
The line is straight because we do not know what happened on the way. The published record gives the start, the two round scores and the finish. It does not give a hole-by-hole card, and no source found supplies one.
A plausible-looking wiggle between those endpoints — a bogey at the fourth, three straight birdies round the turn — would have been the most convincing thing on the page, and entirely invented. It would also have been almost impossible for a reader to identify as fiction, which is exactly what makes it the wrong choice. A straight line is obviously not what a round of golf looks like, and that obviousness is the honesty signal.
Same reasoning for the eighteen ticks along the base: they are a constant rhythm interval with every eighth marked, the 24/8 device used across this library, and the caption says outright that they are rhythm and not a scorecard.
03The facts rule
Atmosphere may be invented. Facts may not. Everything factual traces to docs/facts/dallas-athletic-club.md. As with the rest of this Dallas wave, that file was compiled from web-search result excerpts only — direct page fetches and outbound HTTPS were both refused at the build environment’s network proxy. The 1963 championship details are corroborated across several independent results, including tournament records, and are the most reliable material in the wave.
One correction is worth stating plainly, because it is the kind of thing that propagates:
- Nicklaus did not design the original courses. At least one aggregator states flatly that he “designed both the Blue and Gold courses at DAC.” As written that is false. Ralph Plummer laid out all thirty-six holes from 1954; Nicklaus won on Plummer’s Blue in 1963 and remodelled it two decades later. Reversing the order turns an unusual story into an ordinary one.
- “Mid-1980s,” not 1984 or 1985. Sources give 1984 for the harsh winter that damaged the course and 1985 for the redesign. Rather than pick one and sound certain, the page says mid-1980s.
- “East Dallas,” not a municipality. Directories split between Dallas and Mesquite; the club sits near the line. The page uses the street address or “east Dallas” and asserts neither.
- No claim about what heat does to a swing. The 100 °F is sourced. The physiology is not, and nothing in
docs/facts/neuro-audio-science.mdspeaks to it. Method card 2.2 is about tempo being portable, not about thermal stress. - A card exists for the Blue — with a caveat worth reading. This originally read “no hole-by-hole card for either course,” which was wrong. The database holds three Blue tee rows, and all three repeat the same eighteen yardages under different ratings, with two carrying stale totals. Only the One Star row is internally consistent (6,488 / par 72 / 72.0 / 138) and only it matches the club's published figures, so section 05 uses that row and treats the other two as copies. The Gold has no card at all. The waterfalls at 5 and 11 are sourced as features of the Nicklaus remodel; nothing about how those holes play is.
- The original architect is unresolved. The published record, including the club's own history page, says Ralph Plummer. Our database says Press Maxwell, on both courses. Neither is primary, so the record section prints both rather than picking.
- No other tournaments and no round-by-round scores beyond the final round. None verified.
The most interesting verified number on the page is a contradiction that gets kept rather than resolved: the 1963 championship played at par 71 over 7,046 yards, and the Blue today runs to 6,922. The course Nicklaus won on was longer than the one standing there now. A remodel intervened; the two figures describe two different golf courses sharing a name. Both are printed so the difference is visible instead of averaged into one tidy number.
04The audio
Dallas Athletic Club has no anthem yet. The repo manifest carries dac-anthem with status: "pending" and no file behind it; the deployed host does not carry the id at all, so in production the player filters it out and the queue falls through to Anthem Lab — How It Works, a real streaming track, with the full library browsable behind it. The page says so above the player, before you can press anything.
No invented duration, no placeholder waveform, no substitute music. When a master arrives, the flip is one edit: add its filename to sourceCandidates and set status to ready.
05How it was built
- Hand-written static HTML/CSS/JS — no framework, no authoring build step. ES modules only.
- All internal references are relative, so the site works from a domain root or under a subpath unchanged.
- Every graphic is generated SVG or canvas; no raster media anywhere.
- Fonts are self-hosted woff2 (latin subsets) from @fontsource packages, restored from npm at deploy time via
deployAssets, so deploy uploads stay text-only. - The spectrum canvas is driven by the player’s live analyser and draws nothing when audio is not playing.
- Accessibility: skip link, visible focus rings, semantic landmarks, description lists for both courses and the record, an
aria-labelthat describes the entire scoreboard chart in words including Ragan’s position and the straight-line caveat, and a reduced-motion path in which both lines are drawn complete and every marker is visible immediately.
06Iteration passes
Built to the brief: hero with the built / won / redrew claim block, dark player panel with the pending note, tempo system with 2.2 written around tempo as the portable element, uses written for thirty-six holes of Texas summer, the scoreboard, a two-card Blue/Gold comparison, and the record. The 1963 setup and the modern Blue length are printed side by side deliberately, in their own callout, rather than being reconciled.
Two problems with the wash. The 100°F+ label was right-anchored in the top corner, directly underneath JACK NICKLAUS and his score — it rendered as a ghost behind black display type. It moved to the empty left corner. And the gradient had only two stops, opaque at the top and clear at the bottom, which left a hard horizontal edge across the frame that read as a panel rather than as heat; a third stop at 40% now fades it out in both directions. The duplicated caveat line was also removed from the figure legend, since the same sentence already sits inside the drawing where it travels with the image.
A second search pass found the only per-hole numbers in the entire Dallas wave: five holes on the Blue with yardages and, for two of them, handicap ranks. Four of the five run consecutively — the 8th through the 11th — which is the section.
The honest treatment was also the strongest one. Eighteen columns, five carrying data, thirteen left blank and labelled “not described in any source.” Filling those thirteen with plausible yardages would have produced a better-looking chart and a false one, and a reader could not have told which columns were real. What survives leaving them empty is still the whole argument.
The same pass resolved a date this guide previously hedged. Section 03 says the page writes “mid-1980s” because sources split between 1984 and 1985. The club’s own golf page says the remodelled Blue was open in 1986, following the harsh winter of 1984 — a cleaner sequence, now recorded in the facts file.
Two rendering bugs. The rotated defence labels used text-anchor: end with rotate(-90), which runs text downward from the anchor — they ran straight through the hole numbers, the beat ticks and the caption. And the 5th’s label was longer than its own bar is tall. The second caption line also sat below the viewBox, the same class of bug caught on Brook Hollow — worth checking as a matter of course on any generated figure.
