# Quick task 261024-001: Replace logo references with master assets

## Summary

All logo references in the repository now point to the new master logo files
under `assets/MASTER_FILE-arah2_logo.*`. SVG is used where browsers/Markdown
render it; PNG is used for the Telegram `sendPhoto` path because Telegram's
photo API requires a raster image.

## Changes made

| # | File | Change |
|---|------|--------|
| 1 | `README.md` | Logo `src` changed from `assets/logo_arah2.png` to `assets/MASTER_FILE-arah2_logo.svg` |
| 2 | `.planning/tmp/arah2.wiki/Home.md` | Mirror logo URL changed to the Gitea media URL for `assets/MASTER_FILE-arah2_logo.svg` |
| 3 | `bot/src/bot/commands/start.ts` | Comment and `startLogoUrl` now reference `/MASTER_FILE-arah2_logo.png` (PNG for Telegram `sendPhoto`) |
| 4 | `web/public/MASTER_FILE-arah2_logo.svg` | Copied from `assets/MASTER_FILE-arah2_logo.svg`; served by the Worker |
| 5 | `web/public/MASTER_FILE-arah2_logo.png` | Copied from `assets/MASTER_FILE-arah2_logo.png`; served by the Worker and used by `sendPhoto` |
| 6 | `stitch_minimalist_route_navigator/{active_route_guidance,community_incident_reporter,navigate_map_overview,telegram_live_traffic_feed}/code.html` | Replaced ephemeral Google-hosted placeholder logo with local `../../assets/MASTER_FILE-arah2_logo.svg`; updated `alt` to `arah² logo` in all four mockups |

## Verification

- `grep` across `.md`, `.html`, `.ts`, `.json`, and `.jsonc` files shows no
  remaining active references to `logo_arah2.png` or `lh3.googleusercontent.com/aida/`
  logo URLs. Descriptive mentions in the quick-task PLAN/SUMMARY and in
  legacy-doc paragraphs are intentional.
- `npm test -w bot` passes: 125 passed, 0 failed.
- New public assets exist in `web/public/` and are non-empty.

## Notes

- The legacy files `assets/logo_arah2.png` and `web/public/logo_arah2.png` were
  left in place; only references were redirected.
- The `@assets/MASTER_FILE-arah2_logo.svg` directive was interpreted as the
  conceptual primary asset. In concrete paths: repo-root-relative
  `assets/MASTER_FILE-arah2_logo.svg` for `README.md`, the Gitea media absolute
  URL for the wiki mirror, and the public URL `/MASTER_FILE-arah2_logo.png`
  for the bot's Telegram `sendPhoto` call (PNG is required by Telegram's photo
  API).
