 # CHANGELOG
 
+## 2026-11-10 - One commercial spot per page; Juárez dentist crossing guide (draft)
+
+- Rule: a page shows a sponsor card or a network ad, never both. On the five El Paso/Juárez crossing pages and on sponsored guides, the sponsor replaces the Adsterra unit.
+- New guide (EN and ES): going to a dentist in Ciudad Juárez from El Paso or New Mexico. Covers which bridge to check, documents, how to look up a dentist's cédula, and timing the return. Agency rules link to CBP, SEP and CONAMED. No prices or treatment advice. The sponsor card sits in the guide under the vetting checklist via `<FeaturedSponsor />`.
+- Medication guides place the sponsor with `<FeaturedSponsor />` after the current-wait links.
+- Sponsor links have distinct accessible names (for example "WhatsApp: <business>").
+- Checks: full `npm test` passes after a prerendered build; entry bundle 61.92 KB gzip. Headless Chrome 390px: sponsored pages show 1 card and 0 ads; San Ysidro and the SENTRI guide show 0 cards and 1 ad.
+
+## 2026-11-10 - Sponsored listings, first sponsor (draft)
+
+- New `SponsoredCard` and `src/lib/sponsors.js`: one labeled sponsor per placement, set by port number or guide slug, with optional `since`/`until` dates. Each card is marked Sponsored/Patrocinado and says Border Pulse has not evaluated the business's care.
+- First sponsor: Constandse Esthetic & Dent (Ciudad Juárez dentist), on the five El Paso/Juárez crossing pages (above the ad) and on both medication guides (under the current-wait links). Links carry UTM tags; clicks log `sponsor-click` with sponsor, placement and action (site or WhatsApp), no free text.
+- Privacy notice (EN/ES) now says clicks on sponsored listings are counted with Umami and that sponsored listings are labeled placements from local businesses.
+- Checks: full `npm test` passes after a prerendered build; entry bundle 62.02 KB gzip (budget 62.25). Headless Chrome 390px: card on PDN and both guides, none on San Ysidro, click logs the event, no overflow.
+- Open: the site link points at the clinic's preview deployment until its own domain is live.
 ## 2026-11-10 - Crossing titles and descriptions match how people search (draft)
 
 - Crossing page titles now follow the query shape from Search Console: "<crossing> border wait times today" (EN) and "Tiempos de espera en <crossing> hoy" (ES). Bridges and ports of entry use the name people type: "Anzalduas International Bridge (Hidalgo/Pharr)", "Santa Teresa Port of Entry", "Andrade (Los Algodones)", "Eagle Pass International Bridge II" and others.

 Stock `slate-500` (#62748e) measured 4.47:1 on the light page background, just under 4.5:1, on every page. Light mode overrides `--color-slate-500` to #5e7088 (4.75:1) instead of editing hundreds of class names; `.dark` restores the stock value so dark mode does not lose contrast.

+A page carries a sponsor card or a network ad, never both, and always below the answer. A sponsor replaces the Adsterra unit on its pages. Sponsors are configured in `src/lib/sponsors.js`, one per port or guide, always labeled Sponsored/Patrocinado with the "has not evaluated" line. Sponsor copy states facts only (name, city, links); no medical or price claims in Border Pulse's voice.

 ## The core rule
 
 For most prescription medications, CBP applies a personal-use standard: a small quantity (commonly described as up to a 90-day supply per medication) of an FDA-approved drug, with a valid prescription from a licensed practitioner, may be brought back into the U.S. for the importer's personal use. The drug must be declared at the port of entry on request.

+
+People from El Paso, Las Cruces and southern New Mexico cross into Ciudad Juárez for dental work as a day trip. The dentistry is the clinic's job. This guide covers the part around it: which bridge to use, what to bring, how to check a dentist before you book, and how to time the trip back.
+
+## The short version
+
+- **Pick the bridge by where you start and how you travel.** Walking from downtown El Paso: Paso del Norte. Driving: Bridge of the Americas or Ysleta-Zaragoza. Coming from New Mexico: look at Santa Teresa.
+- **Bring a document CBP accepts for re-entry by land.** CBP lists them under the [Western Hemisphere Travel Initiative](https://www.cbp.gov/travel/us-citizens/western-hemisphere-travel-initiative).
+- **Check the dentist's license before you book.** Mexico's education ministry runs a public [license lookup](https://www.cedulaprofesional.sep.gob.mx/).
+- **Plan the return, not just the appointment.** The wait to come back is the part that varies.
+
+<CrossingWaitLinks items={[["el-paso-paso-del-norte-pdn", "Paso del Norte (PDN)"], ["el-paso-bridge-of-the-americas-bota", "Bridge of the Americas"], ["el-paso-ysleta", "Ysleta-Zaragoza"], ["santa-teresa-santa-teresa-port-of-entry", "Santa Teresa"]]} />
+
+## Which bridge to use
+
+| Starting from | Crossing to check first | Why |
+|---|---|---|
+| Downtown El Paso, on foot | [Paso del Norte](/crossing/el-paso-paso-del-norte-pdn/) | It connects downtown El Paso to downtown Juárez, and CBP reports a pedestrian lane there. |
+| Central El Paso, driving | [Bridge of the Americas](/crossing/el-paso-bridge-of-the-americas-bota/) | Known locally as Puente Libre. It handles passenger vehicles, including larger ones. |
+| East El Paso, driving | [Ysleta-Zaragoza](/crossing/el-paso-ysleta/) | It is the eastern bridge, so it can save a drive across town. |
+| Las Cruces or southern New Mexico | [Santa Teresa](/crossing/santa-teresa-santa-teresa-port-of-entry/) | It sits west of El Paso in New Mexico. Compare it with the El Paso bridges before you leave. |
+
+Ask the clinic which bridge is closest to them and whether they offer a pickup. Some Juárez clinics do, and it changes which bridge makes sense.
+
+If you are choosing between the two central bridges, the hour-by-hour comparison is in [Paso del Norte vs Bridge of the Americas](/blog/paso-del-norte-vs-bridge-of-the-americas/).
+
+## What to bring
+
+- **Your travel document.** U.S. citizens returning by land need a document CBP accepts, such as a U.S. passport book or passport card. The full list is on [CBP's page](https://www.cbp.gov/travel/us-citizens/western-hemisphere-travel-initiative).
+- **Your dental records.** Recent X-rays and a list of the medications you take help the dentist plan before you sit down.
+- **A way to pay that the clinic confirmed.** Ask ahead whether they take cards, dollars or pesos.
+- **The clinic's address and phone number on paper.** Phone service can drop near the bridges.
+
+## How to check a dentist before you book
+
+Border Pulse does not rate clinics. These are checks you can do yourself.
+
+1. **Look up the license.** Every dentist practicing in Mexico has a professional license number (cédula profesional). Ask for it and search it in the [public registry](https://www.cedulaprofesional.sep.gob.mx/). A specialist, such as an implant or oral rehabilitation dentist, has a separate specialty license. Ask for that one too.
+2. **Ask for a written treatment plan and an itemized quote.** It should say what is included: X-rays, the implant, the abutment, the crown, follow-up visits.
+3. **Ask what happens if something goes wrong after you are home.** Who do you call, is there a warranty, and does a fix mean another trip?
+4. **Ask how many visits the work takes.** Implants and full restorations usually take more than one trip, so the crossing becomes part of the cost.
+5. **Know where complaints go.** Mexico's medical arbitration commission, [CONAMED](https://www.gob.mx/conamed), handles disputes between patients and health providers.
+

+
+## Timing the trip back
+
+The appointment has a fixed time. The return wait does not. The chart shows the typical northbound wait at Paso del Norte by day and hour, from the last 30 days of CBP reports.
+
+<BestTimeChart slug="el-paso-paso-del-norte-pdn" title="Paso del Norte: median northbound wait, last 30 days" />
+
+- **Book around the quiet hours** the chart shows, when you have a choice.
+- **Check the current wait before you leave the clinic**, not when you reach the line. Each crossing page shows the time CBP last reported.
+- **Have a second bridge in mind.** If one is backed up, another may be shorter.
+
+The chart is history, not a forecast. Holidays, weather and lane closures change it.
+
+## Bringing medication back
+
+If the dentist prescribes something, the rules for bringing it into the U.S. are in [Bringing prescription medication back from Mexico](/blog/bringing-prescription-medication-back-from-mexico/). Declare what you carry.
+
+## How this guide was made
+
+Wait patterns come from the official [CBP Border Wait Times](https://bwt.cbp.gov/) feed, stored by Border Pulse and summarized as medians. Document and licensing points link to the agency that sets them. This guide does not give medical advice or recommend a treatment.
