Help centers now have a template setting with two layouts. Classic is
the default: the existing hero banner, large search bar and collection
cards. Docs is new: sticky top bar, collections sidebar on every page,
command palette search (Ctrl+K) with a no-JS fallback form, and an
on-page table of contents.
Backend adds a template column (default 'classic', checked to the two
values), threads it through insert/update queries and the request
validator, and resolves page template names as '<template>-<page>' when
rendering public pages. Docs pages also get the published tree for the
sidebar.
Public templates are restructured so each layout is fully isolated and
a third template is just a new directory plus its CSS file:
web-templates/help/shared/ holds the head, announcement, lang switcher,
icons and shared JS; help/classic/ and help/docs/ each hold their own
layout and five pages. The classic stylesheet is renamed to
help-center-classic.css so the head links help-center-<template>.css
directly. Template parsing now globs the help/ subdirectories too.
The admin create and edit forms get a template picker, and classic-only
styling fields (header background, collection layout, card icons) are
hidden when docs is selected.
