ci: touch dist to trigger stage rebuild

el_h1/h2/h3/h4 and el_button were calling el_escape() on their
content, converting any HTML children (e.g. <span class="gold">)
into literal entity text on screen.

These functions accept composed HTML children, not raw text — they
should pass the argument through like el_div/el_p/el_span do.
el_text, el_attr, el_title, el_textarea, and el_img keep escaping
(they handle actual text/attribute values, not HTML children).

-# Pipeline:
-#   1. Stage the foundation El runtime into ./runtime/.

-#      the JS-capable elc binary at bin/elc-linux-amd64 (CI) or the local
-#      elc (dev). Output is gitignored and rebuilt every run.
-#   3. Concatenate src/*.el into dist/main-combined.el (component-first,
-#      main.el last; matches the historical order from build-local.sh).
-#   4. Compile dist/main-combined.el → dist/main.c using the canonical
-#      native elc at foundation/el/dist/platform/elc.
-#   5. Inject the host-side stub forward declarations into dist/main.c
-#      (sed header rewrite, same set as the prior in-Dockerfile sed).
-#   6. docker buildx build --platform linux/amd64 -f Dockerfile.stage.

+ *   - /api/checkout endpoint response shapes
+ *   - /api/supabase-config CORS enforcement

+ * Network mocking strategy: Playwright route() intercepts

+/**
+ * checkout-stripe.spec.ts — Stripe Payment Element + checkout submit flow tests.
+ *
+ * Covers:
+ *   - Stripe.js script presence and NEURON_CFG shape
+ *   - submit-btn starts disabled; enabled after Stripe element is ready
+ *   - payment-message div for error display
+ *   - Founding: attestation checkbox + attest-warn guard
+ *   - Professional: charge timing radio buttons (now/later)
+ *   - buyer-name + buyer-email validation on submit
+ *   - Mocked full payment flow: /api/payment-intent + mock Stripe.js
+ *   - Setup mode (professional, timing=later): label switches to "Save my card"
+ *   - Decline handling: payment-message shows Stripe error
+ *   - /api/payment-intent endpoint contracts
+ *   - /api/link-customer endpoint exists and handles requests
+ *   - /api/attest endpoint (founding plan)
+ *   - Success redirect target is /account?welcome=1
+ *
+ * Stripe mocking strategy:
+ *   addInitScript() injects window.Stripe BEFORE the page loads so checkout-stripe.js
+ *   picks it up. We also intercept /api/payment-intent to return a fake client_secret.
+ *   This lets us test DOM transitions, validation, and submit flow without real keys.
+ *
+ *   For real test-card tests (4242...) the page must have a valid pk_test_ key.
+ *   Those tests are marked with [stripe-live] and are skipped when STRIPE_LIVE is not set.
