doxa-maps-88655c70 78a7baaa96 Fill the chooser's frame: solve the globe's zoom instead of reusing a mercator formula
The chooser's zoom came from log2(width / 512), and the comment above it said why:
"Mercator's world is 512*2^z wide". But the chooser renders under the globe
projection, so that is the same mistake as the region pages framing too wide --
a mercator answer applied to a sphere -- only here it made the frame too SMALL.
Found by looking at the screenshot, not by any assertion: a sphere adrift in
white space.

Measured at 1200x780: the mercator answer of 1.229 put the sphere at 390.61px,
50.1% of the frame's short side, so half the frame was dead space. And the
number was inert -- zoom 0.5, 1.0 and 1.229 all render an IDENTICAL 390.61px
sphere, because Mapbox clamps the globe's apparent size at low zoom, so the
formula's output sat inside the clamp and could have been 0.5 with no visible
difference.

There is no closed form to swap in. Diameter against a clean doubling is 3.6 to
10.5% off above the clamp, because the globe-to-mercator transition is nonlinear
there. What the measurement does establish is monotonicity, which is the only
property a solver needs, so the zoom is now SOLVED against the engine: bisect
the zoom whose limb projection fills 92% of the frame's short side. project() is
pure transform math, every setZoom lands in one synchronous block before a frame
renders, the original zoom is restored in a finally, and the old mercator
formula remains the fallback because a small globe beats a broken chooser.

The first version of the solver measured pole-to-pole and called it the
diameter, which holds only when the centre is on the equator. The chooser
centres on the mean of every people group, latitude 28, so that was a CHORD:
717.6px where the sphere was really 792-835px across, understating it by 1.104x.
The solver over-zoomed and clipped the globe top and bottom -- again visible in
the screenshot while every number still looked right. It now samples the limb,
points at 90 degrees angular distance, and takes the MAX across twelve bearings,
because Mapbox's globe is a perspective camera rather than a true orthographic
one and the silhouette is not a perfect screen-space circle: 396px along the
meridian against 417.3px east and west at one zoom.

Result: the widest axis is 750.6px inside a 780px frame, the whole limb sits in
frame, and dead space falls from 49.9% to under 4%. Pins are correspondingly
bigger click targets. On a phone the ported 1/2 aspect ratio means the globe
fills the WIDTH, which is the right trade -- filling the height would crop it
horizontally and lose pins off both edges -- and that leaves half the height
empty by geometry, which is carded for a Driver decision rather than resolved by
deviating from a clone-faithful rule.

The chooser's behaviour is unchanged and re-proven after the camera moved:
_probe-chooser 15/15 and the new _probe-chooser-pin-opens-country 8/8.

plugin-designs/ — where YOUR maps live

The shared template lives in ../library/ (aliased @map) — you never edit it per-map. You build your map by making a folder here, plugin-designs/<your-map>/, and composing the template's building blocks. Your folder is yours (colors, API, i18n); the template is shared (Apache-2.0, propagated to every map on the next build).

Shared vs. yours — the balance

  library/  (@map)  ── SHARED, reusable, parameterized ──►  legend · map · map-controls
        │                                                    (every map reuses these)
        │  imported by
        ▼
  plugin-designs/<your-map>/  ── YOURS ──►  the map's "main" class (the .vue profile = the Vue
        │                                  instance for that map)
        └── src/            ── YOURS ──►  this map's OWN non-reusable components, colors, API, utils

  One bundle can hold as many maps as you want — add another .vue profile and rebuild.
  • Reusable → library/. The legend, the map, the map-controls are shared, parameterized components every map reuses. Fix once, every map benefits. Never edit it to customize one map.
  • This map's own → plugin-designs/<your-map>/. It holds two things: the map's "main" class (each .vue profile is the Vue instance for that map) and that map's own non-reusable components (in src/). Nothing here leaks to another map.
  • Many maps per bundle. The bundler bundles one map or many — add another flat .vue and rebuild.

Production or experimental — every profile declares itself

Every app profile is one of two things, and experimental profiles are unlimited and encouraged — create as many as you need:

  • Experimental, not built: prefix the folder with _ — the build skips it; it just sits in code. Zero cost, zero risk.
  • Experimental, built: builds normally, but it belongs in the Experimental section of the power app's layout (nav section) — never embedded on partner surfaces.
  • Production: a real product — main sections of the power app + individually embeddable.

(The power app = the SPA layout that composes all profiles into one application.)

The pattern in one picture

plugin-designs/<your-map>/     ← one FOLDER = one BUNDLE, named after the folder
   ├── index.js               ← entry: registers the custom element, finds the profiles
   ├── overview.vue           ← one .vue = one PROFILE (flat in the folder — no profiles/ subfolder)
   └── detail.vue             ← another profile in the SAME bundle

     builds to ─────────────► public/doxa-maps/<your-map>/<your-map>.js   (one file)
  • Folder name = bundle name. Folders starting with _ or . are skipped (handy for WIP).
  • Each .vue = one profile (one map screen). One bundle can hold many.
  • Pick the profile at embed time with the profile field — every profile shares one bundle:
<script src="/doxa-maps/<your-map>/<your-map>.js"></script>
<doxa-map profile-config='{"profile":"overview","tk":"pk.eyJ..."}'></doxa-map>
<doxa-map profile-config='{"profile":"detail","tk":"pk.eyJ..."}'></doxa-map>

Add a map — three steps

# 1. create the folder + one profile
mkdir -p plugin-designs/<your-map>
#    index.js   ← copy doxa-simple-map/index.js, rename the tag
#    <name>.vue ← your screen, built from @map/* blocks (flat in the folder)

# 2. build
npm run build            # → public/doxa-maps/<your-map>/<your-map>.js
#    (just this one:  BUNDLE=<your-map> npm run build:bundle)

# 3. embed the script tag + element (dev staging at `npm run dev` shows a paste-ready snippet)

Your three things (everything else is shared)

  • Colors — how pins are colored. Pick one the template ships (getColorStrategy('language-family')), or drop your own in plugin-designs/<your-map>/src/colors/ (start from template-bundle/src/colors/example-mode.js). Never edit @map/colors/ to recolor your map.
  • API — your map reads its data from the profile-config on the page, so the same bundle points at different data with no rebuild. DataSourceManager accepts csv (bundled file), api (one JSON URL), or rest-api (a live REST endpoint, the default). Prefer the real API over inlined JSON.
  • i18n — the template ships 11 base locales in @map/i18n/locales/. Use useI18n() for strings and RTL_LOCALES for right-to-left; add or override strings from your own profile.

The one hosting variable

The only thing that changes between hosting modes is the <script src>: a relative path when your own site serves the file, or an absolute CDN URL when a partner site serves it. The bundle is identical either way. See ../documentation/CONTRIBUTING.md for the two CDN modes and partner-site embedding.

Profile patterns (mix freely)

  • Individual — one .vue per bundle (simplest).
  • Parameterized — one profile, behavior driven by profile-config props (e.g. tabs[]).
  • Nested — one profile that renders others (workbench-style, like doxa-research-map).
