Covers JR East square badges and Tokyo subway circular badges in the style of Wikipedia's JRSN/TSSN/JRLS/TSLS templates.\n\n## Development\n\nThis is a Val Town project — no build step, no package.json, no node_modules. Deno runtime with strict TypeScript.\n\n- **Push changes:** `vt push`\n- **Stream logs:** `vt tail`\n- **Open in browser:** `vt browse`\n\nThere are no tests or lint scripts configured.\n\n## Notion Integration\n\nA Notion API token is stored in `.env` (git-ignored and vt-ignored). The token is used to populate a Notion database of Japanese rail stations/lines. The DB has three tables: **Stations**, **Lines**, and **StationLine** (join table with Station, Line, and Stop number). Badge PNGs from this API are used as Notion page icons.\n\n## Architecture\n\n`main.ts` is the entry point (default export HTTP handler). Request flow:\n\n1. **main.ts** — URL routing, query param parsing, format dispatch (SVG/PNG/HTML), docs page generation\n2. **badge.ts** — `renderBadgeSVG({style, line, number?, size?, color?, tlc?})` dispatches to the correct SVG renderer based on `style` (\"jre\"/\"tssn\") and presence of `number`\n3. **colors.ts** — `LINE_COLORS` maps 100+ line codes to hex colors; `getColor()` resolves with optional override\n4. **render.ts** — `svgToPng()` converts SVG strings to PNG using `@resvg/resvg-wasm` with Inter font from CDN\n\n## URL Patterns\n\n```\n/jre/{line}.{svg|png|html} — square line symbol (JRLS)\n/jre/{line}/{number}.{svg|png|html} — square station badge (JRSN)\n/tssn/{line}.{svg|png|html} — circle line symbol (TSLS)\n/tssn/{line}/{number}.{svg|png|html} — circle station badge (TSSN)\n```\n\nQuery params: `?size=` (default 30), `?color=` (hex override), `?tlc=` (three-letter code, JRE station badges only).\n\n## Badge Proportional Math\n\nAll dimensions are relative to size `S`. When modifying badge renderers, maintain these ratios from the Wikipedia templates:\n\n- **JRSN** (square+number): border `S/10`, content `S*9/10`, border-radius `S/20`\n- **TSSN** (circle+number): border `S/8`, content diameter `S*3/4`, outer radius fills viewBox (`S/2`)\n- **JRLS** (square only): same frame as JRSN, centered text `S/2`\n- **TSLS** (circle only): border `S*6/25`, content diameter `S*13/25`, outer radius `S/2`\n",[176],"d0807d86-0aa3-11f1-bfbb-42dde27851f2",".vtignore","9370a730-0a81-11f1-b08d-42dde27851f2",76,["D",1771183411907],".env\n.git",[183],"9301fff6-0a81-11f1-aabd-42dde27851f2",".gitignore","930200d2-0a81-11f1-aabd-42dde27851f2",46,["D",1771168705823],".env\n.vt/\n",[190],"ea1ec36a-0aa3-11f1-9ea0-42dde27851f2",["D",1771183454894],[27],"91347eba-0a81-11f1-9062-42dde27851f2",".claude","91347fa0-0a81-11f1-9062-42dde27851f2",12,["D",1771168702832],[200],"pulls","branches","forks","envVars",{"_212":58,"_214":58},"connections",{"_212":58,"_213":58},"count","unfilledCount","emptyCount",{"_40":199,"_31":200,"_29":201,"_135":-5,"_38":39,"_37":202,"_137":117,"_35":279,"_13":58,"_32":33,"_34":-5,"_23":24,"_142":-5,"_229":280,"_26":281},{"_40":274,"_31":265,"_29":259,"_135":201,"_38":39,"_37":275,"_137":117,"_35":276,"_13":58,"_32":33,"_34":-5,"_23":24,"_142":-5,"_229":277,"_26":278},{"_40":266,"_31":267,"_29":268,"_135":259,"_38":39,"_37":269,"_137":24,"_35":270,"_13":58,"_32":20,"_34":271,"_23":24,"_142":-5,"_229":272,"_26":273},{"_40":256,"_31":257,"_29":258,"_135":259,"_38":39,"_37":260,"_137":24,"_35":261,"_13":58,"_32":20,"_34":262,"_23":24,"_142":-5,"_229":263,"_26":264},{"_40":196,"_31":27,"_29":30,"_135":-5,"_38":39,"_37":14,"_137":117,"_35":253,"_13":58,"_32":33,"_34":-5,"_23":24,"_142":-5,"_229":254,"_26":255},{"_40":189,"_31":190,"_29":191,"_135":-5,"_38":39,"_37":192,"_137":117,"_35":250,"_13":58,"_32":20,"_34":194,"_23":24,"_142":-5,"_229":251,"_26":252},{"_40":182,"_31":183,"_29":184,"_135":-5,"_38":39,"_37":185,"_137":24,"_35":247,"_13":139,"_32":20,"_34":187,"_23":24,"_142":-5,"_229":248,"_26":249},{"_40":175,"_31":176,"_29":177,"_135":-5,"_38":39,"_37":178,"_137":117,"_35":244,"_13":58,"_32":20,"_34":180,"_23":24,"_142":-5,"_229":245,"_26":246},{"_40":167,"_31":168,"_29":169,"_135":-5,"_38":39,"_37":170,"_137":117,"_35":241,"_13":172,"_32":140,"_34":173,"_23":24,"_142":-5,"_229":242,"_26":243},{"_40":160,"_31":161,"_29":162,"_135":-5,"_38":39,"_37":163,"_137":24,"_35":238,"_13":139,"_32":140,"_34":165,"_23":24,"_142":-5,"_229":239,"_26":240},{"_40":153,"_31":154,"_29":155,"_135":-5,"_38":39,"_37":156,"_137":117,"_35":235,"_13":58,"_32":20,"_34":158,"_23":24,"_142":-5,"_229":236,"_26":237},{"_40":144,"_31":145,"_29":146,"_135":-5,"_38":39,"_37":147,"_137":24,"_35":232,"_13":149,"_32":150,"_34":151,"_23":24,"_142":-5,"_229":233,"_26":234},{"_40":132,"_31":133,"_29":134,"_135":-5,"_38":39,"_37":136,"_137":117,"_35":228,"_13":139,"_32":140,"_34":141,"_23":24,"_142":-5,"_229":230,"_26":231},["D",1771099583881],"children",[],[133],["D",1771168706731],[],[145],["D",1771099074431],[],[154],["D",1771168706683],[],[161],["D",1771168706806],[],[168],["D",1771168706588],[],[176],["D",1771183411907],[],[183],["D",1771168705823],[],[190],["D",1771183454894],[],[27],"92fb102e-0a81-11f1-b08d-42dde27851f2","populate-station.md","92fb1100-0a81-11f1-b08d-42dde27851f2","91640c98-0a81-11f1-b08d-42dde27851f2",44,["D",1771168705814],"Populate all lines for a station in the Notion StationLine database.\n\nThe user will provide: $ARGUMENTS (a station name, e.g. \"Shinjuku\", \"Shimbashi\", \"Ikebukuro\")\n\n## Steps\n\n1. **Find the station** in the Notion Stations database by matching the name. The station name format is `\"English 日本語\"` (e.g. `\"Shinjuku 新宿\"`). If the station doesn't exist, create it with a 🚉 emoji icon.\n\n2. **Check existing StationLine entries** for the station to avoid creating duplicates.\n\n3. **Research all lines** passing through this station by searching the web.

Set line icons to `{BASE}/{style}/{code}.png?size=120`.\n\n6. **Create StationLine entries** for each line, with:\n - A relation to the station\n - A relation to the line\n - The stop number\n - An icon set to the badge PNG: `{BASE}/{style}/{code}/{number}.png?size=120`\n\n7. **Set icons on any existing StationLine entries** that are missing badge icons.\n\n8. **Research the station's coordinates** (latitude/longitude).
