`min()`	`min(n1, n2, ...): number`	Smallest number
`max()`	`max(n1, n2, ...): number`	Largest number
`number()`	`number(any): number`	Convert to number
`link()`	`link(path, display?): Link`	Create a link
`list()`	`list(element): List`	Wrap in list if not already

`icon()`	`icon(name): icon`	Lucide icon by name
`html()`	`html(string): html`	Render as HTML
`escapeHTML()`	`escapeHTML(string): string`	Escape HTML characters

Any Type Functions

`isTruthy()`	`any.isTruthy(): boolean`	Coerce to boolean
`isType()`	`any.isType(type): boolean`	Check type
`toString()`	`any.toString(): string`	Convert to string

Date Functions & Fields

Fields: date.year, date.month, date.day, date.hour, date.minute, date.second, date.millisecond

Function	Signature	Description
`date()`	`date.date(): date`	Remove time portion
`format()`	`date.format(string): string`	Format with Moment.js pattern
`time()`	`date.time(): string`	Get time as string
`relative()`	`date.relative(): string`	Human-readable relative time
`isEmpty()`	`date.isEmpty(): boolean`	Always false for dates

Duration Type

When subtracting two dates, the result is a Duration type (not a number). Duration has its own properties and methods.

Duration Fields:

Field	Type	Description
`duration.days`	Number	Total days in duration
`duration.hours`	Number	Total hours in duration
`duration.minutes`	Number	Total minutes in duration
`duration.seconds`	Number	Total seconds in duration
`duration.milliseconds`	Number	Total milliseconds in duration

IMPORTANT: Duration does NOT support .round(), .floor(), .ceil() directly. You must access a numeric field first (like .days), then apply number functions.

# CORRECT: Calculate days between dates
"(date(due_date) - today()).days"                    # Returns number of days
"(now() - file.ctime).days"                          # Days since created

# CORRECT: Round the numeric result if needed
"(date(due_date) - today()).days.round(0)"           # Rounded days
"(now() - file.ctime).hours.round(0)"                # Rounded hours

# WRONG - will cause error:
# "((date(due) - today()) / 86400000).round(0)"      # Duration doesn't support division then round

Date Arithmetic

# Duration units: y/year/years, M/month/months, d/day/days,
#                 w/week/weeks, h/hour/hours, m/minute/minutes, s/second/seconds

# Add/subtract durations
"date + \"1M\""           # Add 1 month
"date - \"2h\""           # Subtract 2 hours
"now() + \"1 day\""       # Tomorrow
"today() + \"7d\""        # A week from today

# Subtract dates returns Duration type
"now() - file.ctime"                    # Returns Duration
"(now() - file.ctime).days"             # Get days as number
"(now() - file.ctime).hours"            # Get hours as number

# Complex duration arithmetic
"now() + (duration('1d') * 2)"
