 - Add new gotchas in the right format
 - Understand the soft-dep on `fusion_faxes` + `fusion_pdf_preview`
 - Know the deployment fact that fusion_portal is always co-installed
+
+## 47. Service Booking wizard — two CSS gotchas (client action, `static/src/scss/service_booking.scss` + `xml/service_booking.xml`)
+
+The OWL "Book a Service" wizard renders inside the Odoo **backend** (`web.assets_backend`),
+so the full Bootstrap 5 + Odoo stylesheet is live around it. Two non-obvious traps bit this
+wizard and were fixed in **v19.0.9.6.0** (a first, blind CSS pass in 19.0.9.5.0 did not fix
+the real cause — verify with a render, not by eye):
+
+1. **Never reuse Bootstrap layout class names inside a backend component — namespace them.**
+   The wizard originally used `row` / `card` / `grid` / `btn`. Scoping the rules under
+   `.o_service_booking` does **not** stop Bootstrap's *global* `.row{display:flex;
+   margin-left/right:calc(-.5*32px)}`, `.card{display:flex;flex-direction:column}`,
+   `.grid{grid-template-rows:…}`, `.btn{…}` from also applying (they win for any property
+   the scoped rule doesn't set). Measured live: every wizard `.row` computed
+   `display:flex; margin-left:-16px; margin-right:-16px` — the negative gutter pulled fields
+   to the card edges and flexed label+input pairs. **Fix:** all custom layout classes are
+   `sb-*` (`sb-row`/`sb-card`/`sb-grid`/`sb-btn`). Keep that prefix for any new wizard class
+   that could collide with Bootstrap (`col`, `container`, `form-*`, `badge`, …).
+
+2. **A nested `@media` block must come AFTER the base rule it overrides (equal specificity).**
+   SCSS preserves source order. The responsive `@media (max-width:560px){ .two,.three{
+   grid-template-columns:1fr } … }` was nested high in the file, *before* the base
+   `.two{grid-template-columns:1fr 1fr}` / `.three` / `.timepick` rules. Both selectors have
+   the same specificity, so the later base rule overrode the media query — it was **dead**,
+   and the inner field-grids never collapsed to one column on a phone (fields crammed 2–3
+   across). `matchMedia('(max-width:560px)')` returned true while the columns stayed 2-up —
+   the tell that it's a cascade-order bug, not a media-match bug. **Fix:** all responsive
+   `@media` overrides live at the **end** of the `.o_service_booking { … }` block.
+
+**How it was verified (do this, don't eyeball):** pull the live compiled bundle from prod
+(`env['ir.qweb']._get_asset_bundle('web.assets_backend').css()` returns `ir.attachment`
+record(s) in Odoo 19 — read `.raw`, not a string), render the wizard markup against it with
+the real web-client height/scroll chain (`html,body{height:100%}` → `.o_web_client` flex
+column → 46px navbar + `.o_action_manager{flex:1;min-height:0}` so the wizard's
+`height:100%;overflow:auto` scrolls) at 320/390/768/1280, and read computed
+`grid-template-columns` / `margin-left` / `display`. A standalone vanilla-Bootstrap repro is
+**not** faithful — it rendered fine and falsely cleared the bug.
