The visual convention for redaction is heavy black crossing-out.
Our text colour isn’t always black exactly though (usually it’s very
dark grey, sometimes just dark grey). `currentColor` is a magical CSS
value that let’s us set the background colour to whatever the text
colour is. So both the text and redaction look like they are part of the
same thing.
Couple of subtle visual things here:
- opacity to make the colour better match the text colour – a filled box
naturally looks darker than thin text, so this knocks it back a bit
- an inset shadow to take a few pixels of the bottom edge – the visual
weight of text is biased upwards because text has ore capital letters
and ascenders than descenders – this make it look aligned visually
Because the placeholder highlighting was defined in pixels it got
slightly out of line when it was used at larger type sizes, eg inside a
heading.
By using `em`s it will scale with the size of the type.

Copies the same regex.
Adds some CSS to display conditional placeholders differently to
normal placeholders (vertical rather that curved right-hand edge).
Depends on:
- [ ] https://github.com/alphagov/notifications-utils/pull/40
In research we’ve noticed two problems with the appearance of
placeholders:
1. We are inconsistent about when we display the ((double brackets)).
Sometimes we show them, sometimes we don’t. This doesn’t help user’s
understanding about where the column names in their CSV file come
from, or how they can edit the template to fix any errors.
2. Because they look so different from normal `<textarea>` text, it’s
not immediately obvious that they can be edited just like normal
text. They look more like something that can be dragged/inserted.
So this commit:
1. Makes the brackets always-visible.
2. Makes the text colour of the placeholder `$text-colour`, and only
highlights the name of the ‘variable’, not the brackets themselves.
This commit adds some stubbed data for the pages. The structure of the data
is just a proposal, but it gives the templates something to work with for now.
