Replace the license property sprite (green/blue/red circles) with individual icons

[mlinksva]

Fixes #1322

[Copilot]

Pull request overview

This PR replaces the non-copyable license property sprite markers with text-based glyph markers so that the appendix license table (and other license rule lists) can be copied/pasted with meaningful indicators (Fixes #1322).

Changes:

• Replace license-sprite background-image markers with text glyph markers (✓ / ⓘ / ✕) styled via new .license-marker CSS.
• Update appendix table and license/overview templates to emit the new marker spans instead of sprite spans.
• Remove the old sprite CSS and responsive overrides; add a small “source” arrow marker in the sidebar.

The marker glyph selection conditional is duplicated inline here. To improve maintainability, consider computing the marker character once per type (or extracting to an include) and rendering a variable instead, so future symbol changes only need to be made in one place.

See below for a potential fix:

                        {% assign marker = "" %}
                        {% if type == "permissions" %}
                          {% assign marker = "✓" %}
                        {% elsif type == "conditions" %}
                          {% assign marker = "ⓘ" %}
                        {% else %}
                          {% assign marker = "✕" %}
                        {% endif %}
                        {% for rule_obj in rules %}
                          {% assign req = rule_obj.tag %}
                          {% if page[type] contains req %}
                            <li class="{{ req }}">
                              <span class="license-marker">{{ marker }}</span>

The marker glyph selection conditional is duplicated inline here (and also in other license templates). Consider computing the marker character once per type (or extracting to an include) and rendering a variable instead to avoid having to keep multiple copies in sync.

See below for a potential fix:

                {% assign marker = "✕" %}
                {% if type == "permissions" %}
                  {% assign marker = "✓" %}
                {% elsif type == "conditions" %}
                  {% assign marker = "ⓘ" %}
                {% endif %}
                {% assign rules = site.data.rules[type] | sort: "label" %}
                {% for rule_obj in rules %}
                  {% assign req = rule_obj.tag %}
                  {% if license[type] contains req %}
                    <li class="{{ req }}">
                      <span class="license-marker">{{ marker }}</span>

The marker glyph selection logic ({% if ... %}✓{% elsif ... %}ⓘ{% else %}✕{% endif %}) is embedded inline here, and the same conditional is repeated in other templates. Consider assigning a marker variable once per t/type (or extracting to a small include) and rendering {{ marker }} to reduce duplication and keep the symbols consistent across pages.
