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",[177],"d0807d86-0aa3-11f1-bfbb-42dde27851f2",".vtignore","9370a730-0a81-11f1-b08d-42dde27851f2",76,["D",1771183411907],".env\n.git",[184],"9301fff6-0a81-11f1-aabd-42dde27851f2",".gitignore","930200d2-0a81-11f1-aabd-42dde27851f2",46,["D",1771168705823],".env\n.vt/\n",[191],"ea1ec36a-0aa3-11f1-9ea0-42dde27851f2",".git","ea1ec446-0aa3-11f1-9ea0-42dde27851f2",78,["D",1771183454894],[198],"91347eba-0a81-11f1-9062-42dde27851f2",".claude","91347fa0-0a81-11f1-9062-42dde27851f2",12,["D",1771168702832],[204],"pulls","branches","forks","envVars",{"_216":59,"_218":59},"connections",{"_216":59,"_217":59},"count","unfilledCount","emptyCount",{"_41":203,"_31":204,"_29":205,"_136":-5,"_39":40,"_38":206,"_138":118,"_36":312,"_13":59,"_33":34,"_35":-5,"_23":24,"_143":-5,"_237":313,"_26":314},{"_41":307,"_31":298,"_29":292,"_136":205,"_39":40,"_38":308,"_138":118,"_36":309,"_13":59,"_33":34,"_35":-5,"_23":24,"_143":-5,"_237":310,"_26":311},{"_41":299,"_31":300,"_29":301,"_136":292,"_39":40,"_38":302,"_138":24,"_36":303,"_13":59,"_33":20,"_35":304,"_23":24,"_143":-5,"_237":305,"_26":306},{"_41":289,"_31":290,"_29":291,"_136":292,"_39":40,"_38":293,"_138":24,"_36":294,"_13":59,"_33":20,"_35":295,"_23":24,"_143":-5,"_237":296,"_26":297},{"_41":197,"_31":198,"_29":199,"_136":-5,"_39":40,"_38":200,"_138":118,"_36":286,"_13":59,"_33":34,"_35":-5,"_23":24,"_143":-5,"_237":287,"_26":288},{"_41":282,"_31":32,"_29":30,"_136":199,"_39":40,"_38":14,"_138":118,"_36":283,"_13":59,"_33":34,"_35":-5,"_23":24,"_143":-5,"_237":284,"_26":285},{"_41":275,"_31":276,"_29":277,"_136":199,"_39":40,"_38":278,"_138":118,"_36":279,"_13":59,"_33":34,"_35":-5,"_23":24,"_143":-5,"_237":280,"_26":281},{"_41":268,"_31":269,"_29":270,"_136":199,"_39":40,"_38":271,"_138":118,"_36":272,"_13":59,"_33":34,"_35":-5,"_23":24,"_143":-5,"_237":273,"_26":274},{"_41":261,"_31":262,"_29":263,"_136":199,"_39":40,"_38":264,"_138":118,"_36":265,"_13":59,"_33":34,"_35":-5,"_23":24,"_143":-5,"_237":266,"_26":267},{"_41":190,"_31":191,"_29":192,"_136":-5,"_39":40,"_38":193,"_138":118,"_36":258,"_13":59,"_33":20,"_35":195,"_23":24,"_143":-5,"_237":259,"_26":260},{"_41":183,"_31":184,"_29":185,"_136":-5,"_39":40,"_38":186,"_138":24,"_36":255,"_13":140,"_33":20,"_35":188,"_23":24,"_143":-5,"_237":256,"_26":257},{"_41":176,"_31":177,"_29":178,"_136":-5,"_39":40,"_38":179,"_138":118,"_36":252,"_13":59,"_33":20,"_35":181,"_23":24,"_143":-5,"_237":253,"_26":254},{"_41":168,"_31":169,"_29":170,"_136":-5,"_39":40,"_38":171,"_138":118,"_36":249,"_13":173,"_33":141,"_35":174,"_23":24,"_143":-5,"_237":250,"_26":251},{"_41":161,"_31":162,"_29":163,"_136":-5,"_39":40,"_38":164,"_138":24,"_36":246,"_13":140,"_33":141,"_35":166,"_23":24,"_143":-5,"_237":247,"_26":248},{"_41":154,"_31":155,"_29":156,"_136":-5,"_39":40,"_38":157,"_138":118,"_36":243,"_13":59,"_33":20,"_35":159,"_23":24,"_143":-5,"_237":244,"_26":245},{"_41":145,"_31":146,"_29":147,"_136":-5,"_39":40,"_38":148,"_138":24,"_36":240,"_13":150,"_33":151,"_35":152,"_23":24,"_143":-5,"_237":241,"_26":242},{"_41":133,"_31":134,"_29":135,"_136":-5,"_39":40,"_38":137,"_138":118,"_36":236,"_13":140,"_33":141,"_35":142,"_23":24,"_143":-5,"_237":238,"_26":239},["D",1771099583881],"children",[],[134],["D",1771168706731],[],[146],["D",1771099074431],[],[155],["D",1771168706683],[],[162],["D",1771168706806],[],[169],["D",1771168706588],[],[177],["D",1771183411907],[],[184],["D",1771168705823],[],[191],"ea2db9ba-0aa3-11f1-9d6c-42dde27851f2","objects","ea2dba78-0aa3-11f1-9d6c-42dde27851f2",79,["D",1771183454994],[],[198,262],"ea50feac-0aa3-11f1-86ac-42dde27851f2","logs","ea50ff74-0aa3-11f1-86ac-42dde27851f2",81,["D",1771183455205],[],[198,269],"ea3ac556-0aa3-11f1-9d6c-42dde27851f2","info","ea3ac600-0aa3-11f1-9d6c-42dde27851f2",80,["D",1771183455080],[],[198,276],"ea62e680-0aa3-11f1-9ea0-42dde27851f2",["D",1771183455320],[],[198,32],["D",1771183454894],[224,225,226,227],[198],"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.
